I have found little additional information about a Maria Avery. It is possible she died as a child or young woman, as Solomon Wixom, married to her sister Sarah, had himself sealed to a Maria Avery in 1872, along with eight other women, many of whom appear to be kin to Solomon or one of his wives. It was the custom among the early church members to assure that deceased, unmarried women were provided a husband.
However, she is also likely the Mariah Avery that was first married to Goveneur Butterfield in Schuyler Co, in 1836. He would marry her niece Sarah Avery, daughter of William & Margaret Pickel, in 1845. In the Journal of Solomon Wixom, he recorded the birth and death dates of Maria.
1st Marriage to Mariah Avery: Marriage Vol. 1, p.40. License #00000336
In the 1840 Census, Goveneur Butterfield is shown with a probable spouse, age 20-30, and a female child under 5. Possibly both wife and this child died before 1845 when he married Sarah Avery.
In the 1850 Census, Mr. Butterfield gave his occupation as Bricklayer. He did have one wife and it was Sarah.
