I have found a Jerome Joseph Kolaske married to a Caroline and a child Pauline on the 1910 U.S. Census for Ward Township, Ravalli, Montana. Ancestry.com has the name misspelled as Kebssde, but reading the handwriting one can see plainly that it is Kolaske. Both parents are 28 years old, which fits for the birth years, and Pauline is 10 months (not 4 as the listing says). Jerome and Caroline divorced sometime between 1915 and 1917. I found Jerome in Baltimore in Sep 1918 for WWI draft registration. He MAY have married a Florence (?) and went to Alaska, where I presume he died. Florence is shown as a widow in the 1920 U.S. Census. By the way, Jerome's sister, Helen Lyons, lived with her husband Jim in Missoula, Montana in 1910.
