Hi T
Thanks for your email. Helen here.
As far as I know Joan isn't researching this line now - she was looking on behalf of a relative of hers but Elijah is not actually related to Joan.
I was researching on behalf of an Australian contact and have VERY comprehensive info on Elijah Pryce.......I will have to email the contact in Australia to check it's OK to pass info on to you - I expect she'll say yes

We didn't trace descendants of his daughter but I know we would both be interested to add them to the tree.
I can explain the rumour of a spanish connection as well. I'm not surprised you have some gaps - it is a complicated story....
I'll email when I've heard from Australia
Helen
