I am wondering if anyone knows the father and mother of Gustav Carl Oleson and the maiden name of his wife Mable known as "Lottie" (and possibly her parents?). they came from Sweden; Gustav b. 1855, d. 1920 Colorado, Mable "lottie"b. 1863. they had 7 children. Gustav's name MIGHT have been Grun originally? I would sincerely appreciate any help since I can't go beyond what I know.Thank you all for your help.
