My cousin found several clippings in a relative's family history collection, including one that is partially reproduced here. Ben Siebels was a son of Maria Habben Siebels. Maria was a daughter of Annepken Hinrichs Ufkes (1831-1905). Annepken was a sister to Johann H. F. Ufkes (1838-1924), my 2nd great-grandfather.
The location of Tyro here is Tyro, Kansas. We'll be posting more as time allows. Ben was born in Ostfriesland, Germany. His family came to the United States in the 1910s.
