John and Ann's marriage was published in 1851 and they were living together in 1855. She was born abt. 1829, but from 1860 onward, he lived with Polly L. Jacobs, who was born about 1838. Was Polly the sister of Ann Eliza Wetmore? See here.
Eliza's tombstone says she died Feb. 13, 1886, but her obituary, printed Fri., Feb. 26, 1886, says she died "Wednesday morning", which presumably means Feb. 24, but possibly Feb. 17. When did she really die?
