— born in Huntingdon/Bedford [now Blair] Co., PA:
  6.  (Son B) STROUP, b. 1830-35
  7.  (Son C) STROUP, b. 1830-35
  8.  James M. STROUP, b. 1834/5
  9.  Peter STROUP, b. 1836/7
10.  Samuel STROUP, b. 1837
11.  Mary J. STROUP, b. 1838-41
12.  Nancy Ann STROUP, b. 1840-43; m. 14 Dec 1864, Marion Co., IL, George Harvey BEALE (b. 1840, Juniata Co., PA); lived Baxter Springs, KS
13.  Sarah STROUP, b. 1844; m. Mr. McGRAW

Peter was living in the household in the 1860 census, but not in the 1850 or 1840 censuses, which is hard to explain.  James was not living in the household in 1850, though he did not marry til ca. 1858.  Are James and Peter really their sons?  Secondary sources say, yes.

1 female	30-39	1800-1810	= Jane (b. 1798)

Both Bernard and Jane are listed in the wrong age class, but there's little doubt these are our subjects.  The older girl did not appear in the 1830 Census, so she would not appear to be their daughter, though I suppose it's possible she was missed by the census-taker in 1830.  Certainly, with ten males in the house and a baby daughter, Jane would have need some female hired help!  Listed one line above Shem GRAYBILL, in one direction; in the other direction, three lines down from John GRAYBILL, who is two lines below Joel GRAYBILL.

Where are Peter and James?  James did not marry until ca. 1858, so he should still be at home.  Is he really their son?  Living next door to Michael GRAYBILL (æ 43, b. PA, wife Sarah), who is living two doors down from Shem GRAYBILL, in one direction; in the other direction, living three doors down from William STROUP, who would appear to be their son.

Peter was not living with the family in either the 1850 or 1840 census, so he would not seem to be their son; yet, his placement on this entry says he is.
