Daniel Dean: Birth to 1850

We know Daniel Dean's birth date because of his death certificate. However, that only tells us that he was born in New York.
What do we know and where can we look for more clues?

Birth: 31 October 1823 (Possibly in Yonkers--unconfirmed)


We pick up Daniel Dean Valentine married, yet childless, living next door to his parents-in-law, the Smarts in New York City Ward 18 district 2.

I am still determining exactly where that is.

She is 20 and he is 28. Because of her age, I can't imagine them being married very long at this point.

So we can probably estimate their marriage about 1850 ( or somewhere between 1847-1850).

Did he own the property he was living on? He was a book keeper. From Daniel L. (via Robert Daniel) we know he was a cigar maker. Was he a bookkeeper for a cigar making firm?
