According to what I have found we can rule out Samuel as having marr the sister as his name is Samuel F. He marr Cora ??
I have a "Widow's Pension" that states that the wife of Soloman is Eliza ?? HALL; first husband George I. HALL.
Her maiden name is not mentioned. Might it be SPIKES? An affidavit included states that she and Soloman were marr in Canaseraga 4 Sept 1900 at the Hotel Glenmore.
It is still up in the air who S.A.Farr is; between Solomon and Sylvester.
I have recorded Sylvester being marr to Ellla ?? I don't know is this helps much.
I was surprised that you had an obit for Solomon FARR. I am always looking for them to find the family but never came across one for him. I did not know of any children before your posting. "Mrs. Laura HAGGERTY" is my gr-grandmother.
The hunt goes on for Rufus and Fidelia!
