Thanks for your reply, Sally Jo.
Interesting to me that Rose's sister also married into the Hottmann family. Joe Hottmann is the husband of my father-in-law's Aunt Loveday, so I don't have any more infomation on the Hottmanns. I sent the information from this thread, and from Darcy's recent reply, to Loveday's great-granddaughter, who was pleased to receive it.
Both my husband and his sister have fond memories of visiting Aunt Loveday and Uncle Joe at their farm, when they were children.
