I was reviewing messages on this site when I came across the name Charles Gwilliam married to Elizabeth Dotheridge. I have this Charles Gwilliam in my family tree as the father of John Gwilliam(b.1737) who was married to a Sarah Bennett. I also have Charles Gwilliam's parents listed as Charles Gwilliam and Mary Dalaway. I hope I have this correct. My mother was a Gwilliam, born in the USA as was her father James. Timothy Gwilliam (1843 in Berry Hill, West Dean) was his father. Timothy left for the USA around 1870. His parents, I believe were Timothy (b. 1811 or 1813 in West Dean) and Eliza [surname unknown]. I would like to know if I am on the right track and how I can find out the surname of Eliza Gwilliam.

I would greatly appreciate any help you can give me.
Thanks,
Emily
