Marji, Don't know if you've had an answer or not. Only recently signed on to the mailing list. While browsing the archives I came across your email from January. I also recently signed up with Ancestry.com for their online census images. They have all censuses as scanned images and many have indexes. Unfortunately the 1910 and 1900 aren't indexed. I couldn't find your Kuhefuss on the 1920 index, even using soundex. I found brother Martin Sorley in Washington but they weren't with him. On the 1930 census I found Ann Kuhefusse [sic] as head of house in Seattle, King County, Washington (ED37 page 13B). It is a badly faded and blurred image. But it appears - rents home, age 55, born Wisconsin, widowed, father born Norway, mother born Norway, no occupation. With her is daughter Betty, age 22, born Colorado, no occupation. I could not find Martin Sorley on the index even with the soundex. Also the Boulder County Clerks Office has an online index to their records at - ( http://icris.co.boulder.co.us/login.jsp ) . There are a number of deeds,etc listed for George; he seems to have been in partnership or at least worked closely with a Gunther Carlberg. Also it appears that an August Sorley was the trustee of George's estate. On 7 Dec 1911 there was a document called a "decree" between him and Ann and the 3 daughters. You can write them and get a copy of his will and / or probate ; should pin down death details. Also marriage certificates show on the index but I didn't find any for any Kuhefuss. A guess is Ann left Colorado between 1920 and 1930 and that the 2 older girls married in Washington. Good luck, David
