If John and Rachel lived in Maryland, it argues against him being the John who lived in Philadelphia.

Rept by Capt Wm Hendricks chpt; Mrs Fred Hoch."

The compilers of this volume go out of their way to make it appear as though the volume is a primary source with the official imprimatur of the U.S. Government.  In point of fact, it is a mostly undocumented secondary source.  Here they have mixed up two different John STROUPs, which is clearly evident from the pension record because the John STROUP who married Hannah WINTWORTH in 1801 in Philadelphia also died in Philadelphia, in 1831 (the Battle of Brandywine was fought on 11 Sep 1777 about 25 miles southwest of Philadelphia, in Chester Co., PA).  The John STROUP who married Mary STEELE / STEELY was in Kentucky by 1796, in Ohio by 1799, and died in Ohio in 1832 as is clearly shown in this very sketch.  ["W B L Wt" apparently stands for "Bounty Land Warrant."]
