Hi Leslie, There are many Gibsons in my 1939 Dearborn directory. Do you have any first names? Normally, the city directories list the children who are at home with the parents, but there are no children listed with these Gibsons. If you have any first names, be glad to look them up again.
At this time I do not have any 1940's books for Dearborn. Have 1953 and 1959.
