I am wondering if anyone has any idea if Nicholas Allee, son of William Allee and Susan Bybee was ever married or had children.

I am at a dead end on my Allee search with Albert Allee b. 1843/4. The very first record I have of him is living with Ann (Allee) Leeland and Levi Leeland with what I would think would be his brother, Henry. The census record is 1850 and they are living in Iowa. I think Ann is Albert's aunt but I can not find who his father is and Nicholas is the ONLY brother of Ann's that I can not locate records for...any help is appreciated.
