From June Berry's _Gritmans of Long Island_ I found Harriet Gritman, born 28 Nov 1802 in NYC, daughter of James Gritman and Hannah Golden. On 10 July 1822 she married Theopyhlect [really!] Williamson and died on 24 Nov 1875.

I would be very interested in seeing a list of their children. My great-great grandfather was James Gritman Williamson, who died in Brooklyn at the age of 50 on 22 Aug 1873, but I don't know the names of his parents.

Thanks in advance for any efforts expended.
