I can trace my family in Frodsham back to about 1815 (sorry about the lack of precision --- family history is a back burner thing for me and I haven't looked at my notes on this for years!)
What interests me particularly about your posting is the identification of the names Youd and Yewd. I wonder how you would pronounce "Yewd". Most cheshire people, as I understand, pronounce my name so as to rhyme with "loud". I pronounce it so to rhyme with "dude".
In any case, any other information you have about Youds in Frodsham in the 18th century would be interesting.
PS: the cheshire wills page is interesting. There is a Yewde in Little Budworth 1680, a Yould in Weaverham 1685
