I can't help you with William and Eliza's descendants, but my great-great-grandfather, Richard Vyvyan Hicks was William's cousin.Richard's father Captain John Hicks and William's mother Martha (or Margaret) were siblings.They were the children of William and Ann Hicks of St. Columb Major, Cornwall.My Hicks clan appears unrelated to Eliza's family.
I've been interested in the Rosewarne's since I found that it was the family of Dr. John Rosewarne (William's father) that settled in Cass County, Michigan around 1830 (after a brief stay in New York) and whose reports back to St. Columb Major led to the immigration of their six nephews (my g-g-grandfather and his brothers) to the same area in the mid-1830s.Some of the Rosewarne family returned to New York before 1850.Both Richard Hicks and William's brother Charles were key players in the development of Cass County.Their biographies are included in Cass County history books from the turn of the century.
The families must have been pretty close.Captain John's second son was named John Rosewarne Hicks and Dr. John's first son was names John Hicks Rosewarne.
I found some information on-line about Dr. John Rosewarne and his family a few years back.If you'd like to know the websites, let me know and I'll send them along to you.If you have any information about the Rosewarnes in the early 1800s, I love to know more.
Although not related by blood, if it wasn't for the Rosewarnes, I might be "a Brit" today.
