Thanks! I had everything but the 1900 census entry; hadn't seen that spelling before. Nicolas was also a Civil War vet, has a GAR memorial on his grave (even if it is spelled LOPENDAHL).
Was hoping to find more info on the families his children married into -- for example, Wm. Jacob's wife Helena was a DOLE. Frank Jerome married Christina PUNG, Emma Cecelia married Joseph SIMMER, Joseph George married Emaline SIMMER, Mary Luella married Francis LYNCH, and Myra Isabella married James MEAD. If any of those families are doing family research, will swap.
The other daughters that stayed down in Ohio (Anna, Elizabeth and Elnora) i have fairly well documented.
