Re: Early census Brooklyn, N.Y.
Census for Brooklyn (Kings County) goes back to 1790.
Pre 1850 (1790-1840) the census will only give the name of head of household. All other people in the household are only identified by age, gender and race.
1850 & 1840 census gives ages in a 5 year range (0-5, 5-10) for up to age 20. Gives ages in a 10 year range for adults.
Lists white males, white females, free "colored" and slaves.
There are 4 Ryans listed on the 1840 AIS for Kings County.
