My grandmother is Helen Kathleen and she was their only child. Since I posted I found more information on the Bronson family, but would love to compare information, as most of my info comes from websites. Most have sources cited, however I have not had the chance to confirm many of these yet. I also have some information on the Wildermuth and Newkirk families, Wildermuth dating back to early 1800's and Newkirk dating back to the early 1600's. Most of this information is direct lineage and doesn't deal with siblings, so any other info you have would be wonderful. Look forward to hearing from you... nice to meet some family on here!!
