I am looking for information about Joseph M (Monroe?) Calvin. The earliest information I've found is his marriage to Mary E Boynton in Nov 1897. He was born about 1872. He died between 1930 and 1935. Joseph and Mary Calvin had two daughters, Catherine (1899) and Hedges (about 1901). By 1910 the family was living in Pittsburgh and Joseph worked for the railroad. I would like to find birth and death dates and place; parents of Joseph; and any siblings.
