I am researching the Caisse family in Cohos NY as well.I know that Cleaophas Caisse was born July 18, 1850 and died July 10, 1895.He married Cleophe Breault.I know of 1 child.Her name was:
Elodie (Lydia) born 7/19/1987 died 4/13/55 in Cohoes and she married Henry Poupart.
Elodie (Lydia) Caisse Poupart had at least 6 children: George (the youngest? and unmarried), Homer the oldest; Leah the youngest?; Urban who drowned in early years; Clarence; Edith who was born on 6/12/1899 and married William B. McCarty on 4/6/1921 in Troy NY at the Church of the Holy Cross.
This comes from family records.I would love to know where Cleophas Caisse was born (7/18/1840)and who his parents were.
