Okay, I get it. I don't have this fully worked out but here's a start.
Your query re the Couillard brothers, asking for the list of children to be checked out:
Peter William Couillard was married twice, m1 to Ann Frericks and m2 to Grace B. Saunders. CHILDREN: Charles Reinhart Joseph Howard (called Howard) George William (called William G.) Myrle M. Delores M.
Grover Cleveland Couillard was married twice, m1 to Anna Mary Kazuta (sp?) and m2 to Grace Saunders. CHILDREN: Violet Anna Louis J. Evelyn James Laverne E. Leonard Elaine Marie Oliver Grover Elmer Earl Norbert Robert Lynn Clifford
Is that list of children correct? ============================================= I put the list from the query here so it's easier to compare.
