3.  1860 Census Images (online at Ancestry.com; Image #73 of 73 — indexed "Knoblack"):  Buffalo P.O., Buffalo City (Ward 5), Erie Co., NY, p. 743A, PN 73, enumerated 27 Jun 1860, official enumeration date 1 Jun 1860 (extracted by Diana Gale Matthiesen).  Sharing a dwelling with Jacob LAUTER and family (458/599).

It is very difficult to tell this enumerator's lowercase "a's" from his "o's."  The surnames could be read Knablack, Knablock, Knoblock, Knoblack.  They are listed two households from John KNOBLOCH (æ 39, b. Hesse-Darmstadt), who is almost certainly Charles's brother. 

4.  1870 Census Images (online at Ancestry.com; Image #115 of 424):  City of Buffalo (Ward 5), Erie Co., NY, p. 542A, PN 115, 622/866, enumerated 21 Jun 1870, official enumeration date 1 Jun 1870 (extracted by Diana Gale Matthiesen):

Where was the junior Carl in 1860?  Is he really their son?  "Carle's" brother, John KNOBLOCH, is in Ward 6.

This record is hard to figure.  Daughter Mary (who is fibbing about her age) is shown as having five children, all surviving.  So, where are they?  Are they all married?  The only way for that to be the case is if she had the five children almost back-to-back in the early years of their marriage, then completely stopped having children at least 15 -18 years ago.  I tried to find George & Mary in the 1880 census, but there name is so unreadable here (I don't think "Steifhaus" is even close), that I can't find them.  The next puzzle is son, John, who is said to be married, for two years, but where is his wife?  If he's widowed or divorced, it should say so.  The two children born in the 1890s can't possible be Christina's, so are they John's?  If so, they should have been labeled "grandson" and "granddaughter."
