Hi BT - Are there not records with the State? Perhaps either vital
stats or the Health Dept? I know that NYC records are held in the
boroughs, but the State records are held in Albany, at other than the
courthouse. It's been a long time since I was doing NY research,
sorry, so I'm not sure where you should check. But those two State
agencies might be of use. Best of luck! - Nan
I might suggest checking the US Census for 1870 - indexes exist for the
year in question, though I don't know if you have access to the same
where you are.
There are also listings for the family of a William J. Tyner in the
same city but these may be cousins.
