Lydia's name might be Dutton or Ellis

Since I posted the above message I have discovered that we have three alternative last names for Lydia.Usually I have her as "Lydia K. Dudley", but she also appears as "Lydia K. Ellis" and as "Lydia K. Dutton".I would guess that one of these is her maiden name, and that she had at least one other husband before marrying my ancestor, Rufus Call.

Does this additional hint help you to identify her?
