My gr-grandfather, Calvin II, is Dan's brother. Calvin II was born in Dane County, WI (near Madison) on 11/19/1877. I checked out ancestry.com's 1880 WI census for Sun Prairie and Village of Sun Prairie. There were no listings for Comstock.
Anyway, here's what I know:
My gr-gr-grandparents are Calvin Enos and Sara Cosmtock. Both were born in Canada. They had 3 kids that I know of: Dan, Calvin II and Addie.
I don't know if Addie had any children but Dan's kids' names are Dottie (married a Gleason), Mattie (married Jess Edwards), Effie, Andy, George and Bill.
My gr-grandfather, Calvin II was born in Dane County, WI (near Madison) on 11/19/1877 and died in Scio, Oregon in May of 1940. He lived in Senneca, Missouri for a while. Maybe Joplin as well.
He married Isabel Amanda Waldron on 01/06/1904 in Huron, SD. Isabel was born in Huron in 1886 and died in Bowman, ND on 11/28/18.
They had 9 children:
Iva Merle (married Wm Hewitt)
Orville (married Ada)
John Sterling (never married)
Donald Evans (married Blanche Yarrow)
Walter (married Frances)
Calvin Enos III (married Mildred Jensen)
Phillip (died in infancy)
Electa (Lec) Anne (married Sid Teigen)
James (died in infancy)
Do you have any additional info regarding Dan and Calvin II's family or their father's family (Calvin's and Sara from Canada)?
