Hi Colin
Unfortunately, the 1890 census was mostly destroyed by fire, and very little remains.
1900 Census, New York, Brooklyn, ED 110, Sheet 2A
YARWOOD

Married for 7 years.
Ida, wife, female, white, born Sept 1868 (32) New York, parents born New York. Married for 7 years. mother to 3 children, all living.

Gladys, dau, born Jan 1899, New York
Hary (?)A, brother, born April 1881, New York.
CONLON, Henry (?) Uncle, born Aug 1842, New York, single.
Robert worked in a dry good store, and brother Hary was a clerk in dry goods also.
Home address was: #22, 57th Street.
No sign of Samuel on the 1900 index, sorry.
It is quite possible that Susan/nah has married.
Hope this is helpful to your research,
Valerie
