I'm hoping someone recognizes this family.

Martha Kasten b. Aug. 1887 married Charles Risch b.about 1878 in Wisconsin I believe. They were married about 1908 or 1909. Charles had two children from a previous marriage named Clarence b. May 1903 and Norman b. Dec. 1907. They moved to Montana where Charles and Martha had four more children that I know of. Charles b. about 1915, Lucile b. about 1920, Franklin b. about 1921, and Dorthy b. about 1925. I believe that Charles and Martha stayed in Montana at least until 1935, and moved to Anchorage Alaska sometime after that. From different records that I've found, it looks like Clarence and Norman settled in Alaska, Franklin stayed in Montana, Charles and Martha's son Charles moved to Washington, but I don't have any information on Lucile or Dorothy.
I'm looking for any information on this family, why and when they moved to Alaska, where they lived in Anchorage, information on the daughters, where Charles and Martha are buried, anything would be helpful. I have information to share on Martha's family.
Thank you for your time.
