Our Genealogy Helper

Introduction ...

We have a couple of goals for our Gazetteer:

  • That it be a tool which helps us with planning our trips.
  • We're trying to shape our Gazetteer as a tool to help us understand the community in which our ancestors lived, the community that was part of their daily lives.
  • On our trips, we try to visit those places where our ancestors left their footprints.

By learning about Ontario (and the surrounding area) during the time that our ancestors lived, we hope to have a better understanding of both their community and its relationship to their lifes. We hope that this tool helps to give us an insight into their world.

As we add data and organize our Gazetteer to help with our family research, we will be adding to this our Genealogical Helper for Ontario. While we don't have information that is specific to any given person or family, we intend to expand our understanding about where and how people lived.

Neighboring Counties ...

When searching for family records, we have frequently made the mistake of not checking the neighboring counties.

For example, we have great-grandparents who lived in the northeast corner of their home county. During their lives, most hospitals were in the next county to the east. Almost all of the nearby churches and cemeteries were in the county to the north.

So when searching for records, we had our best success by looking in neighboring counties instead of the county in which they lived:  their home county contained property and probate records; the county to the east contained birth and death records; the county to the north contained their burial records. If we hadn't included the neighboring counties, we would have missed many valuable sources of information.

If you're in a similar situation, we hope that the following information helps.

Ontario is located in San Bernardino County.

To see how the shape of California's counties have changed over time, we recommend the Atlas of Historical County Boundaries.

The following counties adjoin and form the boundaries of San Bernardino County: La Paz (AZ), Mohave (AZ), Inyo, Kern, Los Angeles, Orange, Riverside & Clark (NV).

Below are the counties that are near Ontario. For each of these counties, we show a sample of those communities that are closest to Ontario:

For an expanded list of the communities that are closest to Ontario, see our County-by-County Page for Ontario.

Cemeteries Near Ontario ...

Below are cemeteries that are in the vicinity of Ontario.

This is a new section and is likely to have errors. If you find an error, such as a missing cemetery or we have the wrong name, please let us know. If you know of them, we would also appreciate learning about previous or alternate names.

If you need information about a burial or interment, photos, transcripts, how to contact the cemetery or local authorities, please visit our selection of Genealogy Websites (see below).

If not found below, our Cemetery List for Ontario covers a larger area, with the cemeteries listed in alphabetical order.

The following cemeteries are listed based on their distance from Ontario, with the one closest to Ontario listed first.

Nearby Communities in 1895 ...

We've built the following list with information that came from an Atlas published by Rand McNally in 1895. The Atlas had details such as the population of the community (which appears to have come from the 1890 Census) and whether there was a post office and/or railroad service available. We also indicate if the community no longer exists and is now historic.<5>

The Rand McNally Atlas shows that Ontario had a population of 683 people in 1895 with a post office and railroad service. In 2020, Ontario had a population of 183,393 people.

These communities are listed based on their distance from Ontario, with the one closest to Ontario listed first.

Newspapers Published in the Vicinity of Ontario ...

An ongoing effort between the Library of Congress and the National Endowment for the Humanities (NEH) has resulted in the National Digital Newspaper Program (NDNP).

To share their results, the partnership has created the Chronicling America website. The goal of this partnership is to assemble a database about the current and historic newspapers of the United States. This includes a growing collection of scanned images from selected papers. All of it available to the public on their website.

Using information that we've taken from the Chronicling America website, we've identified 74 newspapers that have been published in the area around Ontario.

We have organized these newspapers into two lists:

  • A Local Newspaper List - focusing on the papers published in the immediate area of Ontario. There are actually two parts to this list - papers printed in the immediate area of Ontario and those printed in the larger area surrounding Ontario.
  • An Extended Newspaper List - a longer list, sorted by paper name and containing those papers published within 18 miles [29 km]<6> of Ontario.

Websites to Help With Your Genealogy Research ...

When we do our genealogical research, we like to start with the websites from Cyndi's List, FamilySearch and Genealogy Trails. These websites offer the information directly or else point to where you can find it. Their information is open to everyone.

To help you get started, the following links will take you to the pages that are relevant to Ontario:

The official website for Ontario: www.ci.ontario.ca.us/

The official website for San Bernardino County: www.sbcounty.gov/

The official website for State of California: https://www.ca.gov/

Footnotes ...

<1>While we're fans and frequent users of TripAdvisor, you should know that we're also members of the TripAdvisor affiliate program.
<2>The location has been supplied by the Geographic Names Information System - which is maintained by the U.S. Geological Survey (USGS). While these values should be definitive, we found that accuracy can vary and you should double-check the location if accuracy is required.
<3>An 'estimated' location is one where we have been given GPS coordinates, but are unable to verify the accuracy of those coordinates. That said, we have some confidence that we have placed the marker near the actual location. A typical reason for being unable to verify a location is that it might be on private property or maybe historic and gone without an obvious trace.
<4>The Find-a-Grave website is an excellent research tool with information about a cemetery's location and interments. They also offer a forum for their members which can provide additional help. More information about Find-a-Grave can be found on their website: findagrave.com.
<5>We use the term 'Historic' broadly and it generally means that the community no longer exists. However, it can also mean that the community might still exist, but was significantly larger or had a more 'official' existence in the past than it does now. Unfortunately our sources of data have proven to be unreliable. If you can provide us with more specific information about Ontario, please let us know so that we can improve our accuracy.
<6>Our distances are not driving distances, but are calculated as a 'straight-line' (or point-to-point) distance. A straight line distance ignores obstructions like rivers, canyons, lakes, et cetera - it's truly a line from Point A (ie- Ontario) to Point B.Our distance measurements begin at a specific point in Ontario. The point we use is located at these GPS coordinates - Latitude: 34.0616, Longitude: -117.6511
