re "Stephen Philpott born abt 1813 in Whitstable/Sandgate (censuses differ) who married Ellen and had kids, Elizabeth, William, Ellen, George, Amelia, Stephen, Richard and James."
I have him on my tree with extra progeny, Frederick, born circa 1853/54 and living with the family on the 1861 census.
My current interest is in James John born 1851/52 who married Charlotte Webb and then Jane Rigden. However, I expect to find in due course that Stephen b circa 1811-13 is the brother of a William Henry, blacksmith, born circa 1807/08 who is a direct lineal ascendent of mine.
The Whitstable Philpott families seem almost certainly to be all related and to converge around the 1790s or 1800s.
