Thanks for your reply, I knew of the marriage for Mary and Joseph Taylor, however I disregarded it because this Mary had several children from 1805 to 1829.
This doesn't fit with my Mary's son George Glue born 1809, I'm sure I have the right Mary as George's mother, but, then again stranger things have happened.
The fact that George and Mary's brother were convicts and the family trees and posts I have seen refer to them as Uncle and Nephew being transported together on a ship named the "Houghley"
