Hi Lalm,
Looking at the gedcom you will see that I have Eliza Trenwith there, but no children to the couple. So, yes please, your chart would help a great deal.
Going back up the Hicks line are you interested in the female lines. For example Woolcock, Bands, Grenfell, Gibbes etc. If so, I can let you have gedcoms for them.
There are also wills on the site for these families.
Obviously, with a large family like Hicks, there will be some errors that need fixing by additional info. The problem is, like all families, the repeated use of Christian names especially in the same generation.
I look forward to getting your info and please do let me know about the other gedcoms.
Roy
