Thank you, Kamil. It has taken me a couple of months to get back to this and sort through things. It looks like I confused Jan and Jun, Apr and Aug. For one of the pathen (sponsors), I thought it was Franz, but you transcribed it as Georg, and that looks right. It seems like the other sponsor was his sister, Katharina (Nemeschkal), so I will be looking for them as siblings of Matheus Votava.
Can we look at Katharina's record again, for the pathen - sponsors? (4th record on left) http://actapublica.eu/matriky/brno/prohlizec/6695/?strana=71
And is the text at the bottom of this marriage record meaningful to genealogy? (2nd record from the top left.)http://actapublica.eu/matriky/brno/prohlizec/6696/?strana=7
