Hi Hope you are still active in your search of Carl Uecker. Do you have any information on Carl's family? I found his family on the 1900 US census, Beadle Co. (Huron) SD. Carl (59) was living with a wife Lena, and daughter, Maria. From what I gather, Carl immigrated in 1881 or 1882, so cannot find him on a previous census. Lena listed she had given birth to five children with four living. I am trying to make a connection with Carl and a Bertha Wallis Uecker Knoke. I doubt if Lena is Betha's mother so am wondering if Carl had another wife. Bertha married Heinrick Knoke at Huron SD. Thank you for the clue on Clayton Co. Iowa. Thanks for any information you may have connecting Carl and Bertha.
