Thank you for responding! I'm sorry I don't know what county.. The best I could find we're census reports from 1840 and 1850 which placed him in whiteside county Illinois. It stated that he was born in 1822 in new York. His wife's name was Sophia, and his youngest son was Alphonso Homer Brooks, which would have been my great great grandfather. I also found draft records from 1863 that stated he was born in NY...I know it's not much to go....I just don't know what step to take next. Thank you for any help / advice!
