We are the Minnesota branch of Brockmans. My husbands grandfather was Charles Brockman, brother of William who married Priscilla Sickler. Charles married Priscilla's sister Etta. Your grandmother Roverta was William and Priscilla's daughter is that right? I know that William and Priscilla moved to CA. They have one infant burried in the Lakeside Cem. at Fairmont, MN My husband and his parents visited Brockman relatives in 1951 0r 52 in CA. He said Uncle Bill was deceased by then. I have not had much sucess in getting a response from relatives. There were 9 children in Charles and Etta's family they are all deceased. Let me know if I can be of any help..
