Thanks Ann, the addition of 2 more children in the late 1760 fills a bit of gap between them getting married (1765) and the 1st child I found who was William in c1773.

I'm just a bit worried that I've now got an Eliza and and an Elizabeth, although I seen this before in family trees. Just got to double-check a few things now to make sure I've not got confused!

If you want a copy of the tree I'm compiling e-mail me at
