I don't know if there is any connection, but I two Edward Hipkins.Both were lighterman on the Thames. The first was born in 1734 & his son (also Edward) was born in 1759. There was another Edward Wilkins Hipkins, born 24 June 1810 in Southwark, London. He was relatedto the two above), but not certain just how.
Have you been able to trace "your" Edward back in England?
