I had already checked for a death certificate for both of them, with no luck. My husband's grandfather was Charles Loren Ferguson, son of John and Mary Jane. Do you have any information on Mary Jane's mother, Louisa? If you don't, I do. We need to swap email. I have quite a bit that I've been able to gather, but most of it's on Charles Loren. However, I do have information on Louisa.
