Genealogy Public Records Information?

public records search
Serenity asked:


On a recent search on Ancestry.com, I came up with severals slightly disturbing public records. Two showed my brother’s x-wife (divorced about 17 years ago) listed with my parents, at two of her recent addresses and another showed her at their current residence. All three addresses also list someone I’ve never heard of with my family’s last name. My x-sister-in-law still uses our family name, even though she’s been married several times since she was married to my brother.

Just for info - the divorce was not amicable and my parents have avoided contact with her as much as possible since the divorce.

My questions are:
1. How can I find out what public records the ancestry record reflects?

2. What possible reason could there be for my parents names to be listed with hers on homes that they have never had anything to do with?
