The Doty's of North Chili

I began to research our family in the summer of 2007. The immediate names are: Doty-Lockwood-Walker-O'Grady. We have built on other's research to follow the Doty's of Rensselaer County NY back to 1620, and are now following Walker back through the Womeldorfs of Centre County PA. I'm looking for information on my great-grandfather--a Walker who married Sarah Womeldorf around 1884, and on my great-grandmother, a Flavia Moss who married William Lockwood in the 1880's. Please be in touch if you are on a similar journey!
