Hello, her birth date is 7 September ("narozena dne 7. téhož" = born on the 7 day of the same [month]). She was baptised on 9 September 1743, which was a 2nd Monday after the 13th Sunday after the Pentecost. I must say that this is a really complicated way to determine the date by the parish priest. The Easter Sunday in 1743 was on 14 April, and you go from there. You correctly noticed that her first name is Maryana (standard spelling "Mariana"). The standard form of the surname would be "Houšková", as the digraph "ou" used to be transcribed as "au" until the 1840s orthography reforms. Her father is Vojtěch Daňhel Houška ("otec Vogtiech Daňhel, hospodarz na zywnosti Daňhelowske, przyrozeny geho przigmieni dle przedkuw geho gest Hausska" - this means that he took the possession of a farm previously held by the Daňhel family, probably when the former owner died childless and the property got reassigned by the lord from one serf to another. Her mother is Lydmila (standard spelling "Lidmila").
