I do have the death certificate of my Joseph and on it is listed his parents as Benjamin and Annie (Butterfield) Bartlett. Joseph was born Feb.17, 1837 in Buffalo, Erie Co., N.Y. He was Married to Julia Amelia Bliss on June2,1862 inWalworth,Dodge, Wisconsin.His father, Benjamin, was born in Vermont around 1812 and Annie in Vermont around 1817. Ben and Annie's other children were Manita, Norman, Clark, Abbie, Matilda. Jospeh and his wife finished out their lives in Lake City, Wabasha Co., Minn. He died May 9, 1912 and she Feb. 8, 1919. I don't think Joseph is the missing son but what about Benjamin?
