Census Records:

1820 NY Oneida, Westmoreland
1830 NY Oneida, Verona
1840 NY Oswego, Parish
1850 WI Winnebago, Neenah
1860 WI Outagamie, Appleton
1870 WI Waushara, Poy Sippi
Widow "Filinda" appears:
1880 WI Portage, Stevens Point

Based on the birthplaces and ages of their children, Harvey and Philinda apparently moved from New York to Wisconsin between 1841 and 1846.

There are many family trees at Ancestry.com which claim Harvey died at "Portage, Wisconsin," but in the 1880 census, his widow Philinda is living at Stevens Point, Portage County, Wisconsin. I'll look for a pair of graves there.
