Thanks ReadyDale and Dawn. The 1775 marriage is starting to get into the correct time zone. Should have thought that Chatters would go hiving off and look for the marriage and hence said that Mary married in 1790 in Plymouth and Sarah in 1799 also Plymouth. The 2 Uncles both married in London. Thomas Jnr other than being Executor to the 1808 and an 1810 will is a mystery. Thomas Snrs brothers were William and Joseph of Greenwich (1742-1810). William and Arabella Rigge (1784) had 10 children. Joseph first to Mary Cox (1786) and then Ellen Smith (1792) looks like none, or none that survived to 1810 I should say. (Joseph and Cornelia Crawley have been eliminated as parents to Thomas, Joseph and William despite having all 3 themselves)
