Welcome to the Thayer Families Association!

We Are A Bundle Of Our Ancestors

Please be aware that throughout the website, words Like this, or this, usually are links to another pertinent page.

We invite you to embark on a once in a lifetime journey tracing your Family's past. The Association was founded in 1991 and is the result of many dedicated Thayers as well as non-Thayers with a common goal to see where they came from and the history involved in this truly remarkable surname. The TFA founders stated goal was  “To sponsor the development, publication, and distribution of a rigorously researched Thayer Genealogy” so that anyone could learn about their ancestry and the history of this truly remarkable surname. TFA is a Family Association, incorporated in the Commonwealth of Massachusetts, as a non-profit corporation, under the name "Thayer Families Association".

Everyone in the Thayer Families Association is offering you a wonderful experience to meet your cousins, some you may already know, and some you probably have never met, or even knew existed.

With members across the United States plus Canada and Ireland, the Thayer Families Association welcomes all who have an interest in Thayer families, including all variant spellings. Please check out what we have to offer. We hope you will return to see the additional features as we go forward. If you have suggestions or comments, please contact us HERE.

Your TFA Board of Directors made the decision to postpone the 2025 reunion for one year to give our hosts opportunity to heal and recover. Your prayers for their healing and restoration would be greatly appreciated. We anticipate the reunion to be held in Nebraska September 2026 with more details to follow as they become available.

Brigadier General James B. Thayer

This is a tribute to retired Oregon Army National Guard Brigadier General James B. Thayer, who was the guest of honor at the All-Star Salute to the Oregon Military event held May 18, 2012 at the Oregon Golf Club. The event kicked off the Capital Campaign to raise funds for the new Oregon Military Museum in Clackamas. He was joined by his son Tommy Thayer, lead guitarist of the rock band KISS, former Oregon Governors Vic Atiyeh and Ted Kulongoski, golf legend Peter Jacobsen, and many others. This tribute gives a historical look back at the life's accomplishments of a soldier, father, friend, respected local business owner, and WWII hero.

Three generations of Thayers have graduated from the UO, beginning with Brigadier General (ret) James B. Thayer '47, and continuing through sons John '81 and Mike '85, and most recently twin grandsons Matthew '11 & Patrick '11.
