Hey Paul, where does the name Marquering come from? Are you sure? since it seems to me different. I would read:
#74. [1805] geb. den 19. Aug. mittags 12 Uhr.; get. den 25. Aug.; Albertine Willhelmine Mengering; Eltern: Friedrich Mengering, Musq.[uetier] v.[on] d.[es] H.[errn] Hauptm.[ann] v.[on] {Poenike} Comp.[agnie], mit s[eine]r. Ehefr.[au] Sophia Bernhardtin.
Translation: On August 19th 1805 at 12 noon was born, and baptized on the 25th: Albertine Willhelmine Mengering, daughter of Friedrich Mengering, musketeer under the compagny of the captain Mr. von {Poenike}, and his wife Sophia, née Bernhardt.

notes: the book is from the military priest of the Prussian Infanterie-Regiment No. 34 "Prinz Ferdinand" which was stationed in 1805 in Neu-Ruppin. So the birth and baptism took place in that city. I'm not sure about the name of the captain, this would need more crosschecking.
The last column of the entry gives 8 Godparents, but this is simply not decipherable.
