Edward Tivey (b 1691) appears in my family tree (my paternal grandmother was a Tivey from Leicestershire) and my name is Elizabeth Jacques, so it's really spooky to see how a relatively unusual name can crop up more than once within one branch of a family tree. Bizarrely my mother's maiden name is Ann Edwards and this name also appears a few generations later - someone with that name married John Tivey (brother of Edward Tivey b 1753)...
I had not been able to trace who Edward Tivey was married to or who his other children were (apart from Thomas) so you information is very useful. There is a website on the Tivey family that you may find useful:
