Reinland #23 (Landless) Johann Vaehr, born 4 Feb 1813 Maria Wiens, born 18 Jul 1811
This implies that Johann's birth date in the Reinländer Gemeinde Buch (23 Jan 1813) is according to the Julian calendar, which appears to be unusual for the Reinländer Gemeinde Buch. (It is also possible that 4 Feb reflects a double application of translating from Julian calendar to Gregorian calendar (that is, 12 days added twice).)
