Hello, I just joined the list. I have been trying to follow my great grandfather, T. L. BUCHHOLZ, and family on their wanderings around Minnesota and South Dakota from about 1889 through 1937. He operated several hotels, including the Wentworth in Sioux Falls and the Columbian in Ortonville, during a period from about 1904 through 1912. Among the mementoes the family collected is a postcard menu from the Riverside Hotel in Montevideo, Minnesota. There is no date on the card. My question, are there resources available for this time period, such as city directories or business directories, that would list businesses and their operators? I would like to find out the dates that the family operated the hotel. Jim Bellingham WA (Yes Washington state) [email protected]
