Secondary sources disagree as to his birth/death locations.  Note also that Sleepy Creek is in Morgan Co., WV, and that Frederick Co. is in VA. 

Father:  William ROSE (1680- ) of England and Philadelphia, s/o Sir Hill ROSE (c1650-1720) of Liverpool, England
Mother:  Jane __?__
Migration:  arrived Philadelphia 3 Dec 1699 on the ship, Canterbury, Capt. Fryers, master

but they cannot be his parents because Jane cannot have been married in 1699 and still be young enough to bear a child ca. 1731.  Also, William is buried in Philadelphia, so presumably he died there, so presumably any of his children would have been born in either England or Philadelphia.

Ezekiel cannot be our subject's son if he was born in 1735, but the birthyear of Ezekiel's first child (in 1774), suggests Ezekiel's birthyear is the error, rather than the connection.
The 12/13-year gap between Abigail and Robert is suspicious — is he really their son or did Ezekiel have a second, younger wife?

Said to have this son, but connection not accepted by all:
.  John David ROSE, b. 1 May 1761, Augusta Co., VA [now Harrison Co., WV]
The existence of Maj. John ROSE would seem to argue against this John being our subject's son.  Also, it appears most of the above moved on to Ohio, while John David did not.  John PRIOR, a son of Abigail (ROSE) PRIOR, apparently lived with Maj. John after she remarried, which argues that Maj. John is our subject's son, rather than John David.
