Here is what I have on your family: Henry's father is James WB and Ann ? of Rotherhite, Eng.You can check the firstname.lastname@example.org webpage files for information on the DNA link which I recall shows a connection between this line and the Virginia USA line.
Henry was born 1756 Rotherhite England, christened Aug 27, 1756 in Rotherhite,married Sarah Brocoli in London, and I believe he died in England, although I have no proof to offer.
my information came from Ruth WB of Australia who says: Ruth Westbrook from Australia. I descend from brothers James Westbrookmrd Elizabeth Chapel and Samuel Westbrook mrd Mary Mason from England in 1818 (James) and 1829 (Samuel). There mother Sarah (nee brocoli) also came out and died in Tasmania in 1836. Hope this is of some help
