Ok, I was doing a little more work on the WILLIAMS line. It turns out the wife Mary Elizabeth surname is ISNOR not SMITH. I've found this surname on a few of the children's marriage and death records. Hmm...
I'm still pretty sure that it is the right HALL family living next door to them though. So if this is the same WILLIAMS family mentioned in the estate, who is Elizabeth?
John WILLIAMS and Mary Elizabeth ISNOR had a daughter named Eliza Ann but she married a Robert CAMPBELL.
So unless Mary Elizabeth was married twice, her surname being SMITH and first married name ISNOR they she wouldn't be the Elizabeth Williams we are looking for. I've seen first married names turn up in vital records as the mothers surname before.
So I'm wondering why the HALL family moved from Amaranth twp. to Artemesia twp. to live beside them. If Elizabeth isn't a SMITH, perhaps she is related to Thomas SMITH's wife Mary surname unknown. Or she could be related to the HALL side some how. With John WILLIAMS being from Germany, I don't think he would be a blood relative.
I'll keep looking for the right Elizabeth Williams.
