My mom's cousin, Jane Margaret Bergiven, married twice, first to a William Duso, and secondly, to a William Dettmer. The data posted for William Duso doesn't appear to be for Jane's husband William Duso. I've not been able to locate the right William Duso, the father of her children. The one born in 1913 and dying in 1980 has findagrave.com information indicating another wife and different children. Can someone help?
