Back again. Found online the 1855 state census for the Town of Cazenovia, Madison Co., NY:

(URL trails off on printed page--may be whole thing above though)

In it are:

Olcott, Jared, District #2, Dwelling #354, Family #383, Page 82, Line 4, Frame Dwelling Valued at $200, Age 63, Resident 7 Years, 5 in Household, Occupied as Farmer.

Olcott, Riley, Distrct #2, Dwelling #353, Family #382, Page 82, Line 1, Plank Dwelling Valued at $150, Age 24, Resident 10 months, 3 in Household, Occupied as Farmer.

I'd say this is Jared, Jr., son of my gggg-grandfather Jared Olcott, b. 1759, and very possibly Riley is Jared, Jr.'s, son. I've not followed this family. But Jared, Jr., may have moved directly to Cazenovia, Madison Co., from wherever he was previously in Oneida Co.

At http://www.rootsweb.com/~nyjeffer/revfm.htm there are some snips (uncorroborated) about Jared, Sr.'s, Revolutionary service. It also includes this info:
"The following children were living in 1853 [but doesn't say where]:
Jared Olcott
Nancy Putnam
Delia Stone [guess this might be where my gg-grandmother Delia Matthews Budd's first name came from--would have been her aunt; Delia Matthews Budd's mother was Jared Sr.'s daughter Polly Olcott Matthews, who d. in 1851]
Edward Olcott
Marinus [?] Olcott
Mary Emerson
Franklin Olcott
Cornelia Griswold"

Now I'm not so sure that Jared, Sr., had a son named Joseph (was from memory--maybe a bad one), though the above is not a full list of his children, only the living ones in 1853. I think the Joseph mentioned in the previous posting might well have been Jared Sr.'s brother, though.
