hello, the only reason i am answering is because of the iowa census and the names. this might be a lead for you. isaac pulver b mar 9.1801 in kinderhook ny m hannah armstrong april 27, 1840, in richland county ohio. two of their sons died in iowa, isaac leroy b feb 9, 1848 m sarah catherine lutz d feb 24, 193- buried in keota keokuk iowa. and simon clark pulver b dec 19 1851 in richland county ohio m mary cornelia mcfarland buried in oakville iowa. also just as an aside the two sons sister's name was olive, who also married a mcfarland. hope it helps or gives you a lead. if you find out that either of these two were the line then i can give you the pulver line all the way back to 1709.
