<< What kind of indexing is available for the Brooklyn Eagle during the years
The Quens Co. public library in Jamaica, NY has a manuscript index of death
notices in the Brooklyn Eagle, compiled by Gertrude Barber in 1965. I don't
know the complete range of years it covers, but I have found entries from
1844 to 1880.
I hope this helps.
P.S. I'd be interested in knowing if anyone knows of any other indexes.
