I can help a little. George and Susan Perrin did indeed have a daughter named Elsie. She has a rather sad story and is the subject of the current addition to my 'Perrin Memory Book'. I have Elsie's lineage all the way back to John Perrin Sr. of present-day Washington Co. MD.
I'd love to hear from you. Contact me at firstname.lastname@example.org
My great-grandmother, Alice Perrin Spielman, was Elsie's oldest sibling.
