That's the only one I could find. CatOne
Searched all Thomas gaskill's of abt same age -found a few "boarders" b. lancs -but none married.
I wonder if margaret Towers was really Ann gaskills great Aunt -she could be the Aunt of Ann's mother margaret

??
Think there's a lot more research needed to "tie " them together
Have you thought of making a post asking for baptism records of all the children -Father Thomas /Mother possibly margaret/Elizabeth???
It's worth a try
