Number 21. 1922, born 25 June 3 a.m., baptized 1 July.
Eleonora, Catholic, female, legitimate
Father: August Nitterl, Catholic master shoemaker in St. Oswald number 24, legitimate son of Anton Nitterl, innkeeper in Ochterbach, parish of ??itz, and of Aloisia wife born Ertl. Born 7 V 1887.
Mother: Eleonora wife, Catholic, legitimate daughter of Georg Schuldenzucker, master miller in Mühldorf number 20, parish of Nieder??, and of Maria wife born Hofstätter. Born 29. I. 1889.
St. Oswald number 24.
Maria ??, Cath. farmer-woman in St. Oswald number 18.
Maria ?? ... [sorry, not really even trying]
Marr[iage of parents] 25 III 1915 in Nieder??a
?? St. Oswald 4/7 1922 Alois ?? [sorry; I did try on this one, but didn't get anywhere much].

Yeah, no. I routinely skip the officiant or registrar in my translations, as his name is a distraction at best. (I tend toward obsessive completionism, but there are limits.)

The little inserted letter on the marriage location turns out to be another 'r': Niederranna. Matricula-Online has it as "Muehldorf-Niederranna", and the marriage of August Nitterl and Eleanora Schuldenzucker is the first entry on page 91 of the 1882-1938 marriage register (Matricula Online / Österreich / Niederösterreich (Westen): Rk. Diözese St. Pölten / Muehldorf-Niederranna / Trauungsbuch | 02-16 / 02-Trauung_0091).

Based on its "Oxenbach" and what I can make out from the 1922 birth record, Anton's location is Ochsenbach, and the something-itz parish is Ferschnitz.

August's birth on 7 May 1887 in Ochsenbach house-number 7/7 is the last entry on page 4 of the 1887-1928 Ferschnitz birth register. His grandparents were Mathias Nitterl farmer and Josefa born ?affetseder(??), and Johann Ertl merchant and Aloisia born Kellerr(??). The entry records places for them, but I haven't been able to figure them out.

Eleanora Ertl's birth on 29 January 1889 in Mühldorf house-number 20 is the last entry on page 122 (image 124) of the 1877-1905 Mühldorf-Niederranna birth register. Her maternal grandparents were Karl Hofstätter farmer and Josefa born Siebenhandl. Again, there's a location that I can't make out. I don't know why her father's parents aren't recorded.
