Hello COusin,
I think I have you in my Family tree. Were your parents Fred and Anne Coster? WOuld your Grandmother be Emma Francis Seabrook? Im Bill, son of Ellen andf Frank Seabrook. My parents used to visit Fred and Anna a lot when I was younger. They lived in Conn.
How were you able to find out about John's father being another John? My earliest entry in my tree is John Braley Seabrook boorn 1803. He Married Mary Anne Parsons. Can you go back much further? I would really appreciate it if we could exchange info. Im finding it easier to perform Family Trees on other Seabrook branches than my own.
Talk to you soon
Bill Seabrook
