The Lucina Markham born in the 1840s was likely the Lucina who was the daughter of Harrison and Marie Olive Markham. This Lucina married John Weed, who was born in New York in 1829. The 1880 census shows a John A. Weed and wife, Lucina, residing in Whitney / Bay City, Michigan. At the time, only one child was listed, named, "Jenisha", who had been born 5 June 1875, in Augres, Arenac, Michigan (apparently the mother's name is recorded as "Lavinia"). But John A. Weed also had a son named John A. Weed, who was born in Michigan in 1881. This John A. Weed married Alice L. Weed, and (per the 1820 census) they had children named Viola E., John E., and Irving V.
