I am looking to find other relatives of William Kooi (Rothbury, MI) son of John L. Kooi and Susie (Swantje) De Haan. Apparently there were a few children that died in a fire. There was supposed to be a total of 14 children, but I can only research 12. I am William Kooi's granddaughter.
I have a lot of information on the family over 350 extended members down various paths.
