Peter, once I re-read both yours and my last post, I got to thinking about the lodger, Lucy, and looked up to see if there was a marriage record in Platte county for her.
Platte Co. Marriage Records
Book 6, p23. #203
SAMPACK Charles H. & MIMMICK Lucy
22 Nov 1899 Columbus
Charles 21; Columbus; Pol; Charles Sampack; Anna Mucha
Lucy 23; Columbus; Pol; Joseph Mimmick; Mary Laganza
So, this leads me to ask this question: Can we assume that Joseph Mimmick and John Mimmick one and the same?
