1 male	19-25*	1794-1801	= ?

1 female	16-25	1794-1804	= Margaret (b. 1799)
2	personss engaged in manufacture
*In the 1820 Census, the third column is age class 16-18 and the fourth column is age class 16-25; therefore, any individual in column three is duplicated in column four.  By subtracting the number in column three from the number in column four, you can create an age class "19-25."

Jacob's father died 1819/20, so he may have his younger siblings living with him.  Listed next to brother, Samuel STROOP, however, the list was roughly alphabetized, so proximity on the list may not indicate geographic proximity, beyond being in the same township.

The Millerstown Ledger (Perry County Newspaper) reported: "We record this week, the death of Mr. Jacob Stroop, uncle of Mrs. William Goodman of this place, and Capt. Geo. Stroop of the Tyrone Democrat, which took place at his residence at Ottowa, Illinois, on the 11th of September, at the advanced age of 82 years.  Mr. Stroop moved from Perry county to Illinois about 20 years since, was married twice, his first wife being Miss Loy, of this county, and the last, Mrs. Littlejohn nee Miss Carothers, of Carlisle; this lady died last June -- Many of the old residents of Perry County will doubtless remember this gentleman.  His disease was disentery."

Administration on the Estate of Andrew Mateer, late of Landisburg, Tyrone Township, Perry County, Pennsylvania was granted 18 August 1821 to Jacob Stroop Esquire; bond for $1200 with John Shuman and Henry Lightner as sureties.

I'm running across records for a Jacob Stroop SHUMAN, so there must be a familial connection here somewhere (e.g., is John SHUMAN Jacob's son-in-law?).
