Daniel's widowed mother is living with the Thomas MORROW family, so I've no clue who the elderly women, here, are.

Wm Stroup	27	M				Pa
Stew Stroup	21	M				"

Is "Stew" supposed to be "Steve"?  They are living in what appears to be a boarding house.  Now that our subjects are deceased, the unmarried children appear to have scattered.

Rockland... Daniel Stroup, 5 Sept 1789 - 6 Mar 1843 Elizabeth Rose Stroup, 15 May 1792 - 24 Jan 1847, w/o Daniel

It is clear from the form of these records that these are not verbatim tombstone readings, but compilations based on tombstones and other unknown sources — so caveat emptor!
