My family has coulons in L.A CA. Hopefully this will be some help, I have Levi Frances Coulon born in 1891 of Dec 1st in Norwalk Ca. Also Stella Irene Coulon Then my Grandfather and his bro's and Sis's were born in Norwalk in L.A.and Lamoore CA in early 1900's. I go back as far as Frank Coulon in 1858 Showing he was born in Ill. Then moved to CALIF. and marrying Cora Mulkins in Long Beach. If you can find ties from Frank that would be great.
