With all due respect, the point of these message boards is to connect with others who have a connection of some sort. Federal census information, while invaluable, is easily found on this website or many others.
Mrs. Rhoda Brooks was my 4th great grandmother. Last June I spent an afternoon in the Wayne County Historian's Office in Lyons, NY. It was there that I confirmed that this lady was indeed the mother of my 3rd great grandfather and I did this via her surrogate papers. With the surrogate papers, I learned her date of death and the identity of all of her children. I also obtained a microfiche copy of the 1855 New York State census with her name, birth date and birth place on it.
It is entirely possible that there is another descendant of hers out there that has found another scrap of information or might even own a family bible.
