About Me

My name is James Colgan, I live outside Philadelphia, Pennsylvania — and I write about various genealogy and history-related topics.

I share any possible research notes, record copies, clippings, and more — so if you are researching a surname or individuals on whose records I’ve done work, feel free to ask if I might have what you’re trying to find.

In addition to the 3 separate Colgan families on my personal tree, I do regional One-Name Studies for the Greater Philadelphia area and Western Maryland on the surnames Colgan and McColgan. So I am happy to share if you get in touch and let me know what names, records, and research you would like. It doesn’t matter if they are on my own tree or not; if I have research on your research subjects, I am happy to freely share.
