Yes, priests are busy, but a 1944 record is probably in English and you have the exact date, so I vote you try. If you were fishing in a range of years (like "between the 1900 federal census and the 1905 state census") in the time period where the records were likely to be in old German handwriting, but the language is Latin, now that would be a different--much harder--search! Wait until after Easter, and prepare to be patient. Check the book The Catholic Church in Wisconsin by Harry H. Heming for church founding dates etc. It was published in the late 1890s and is organized by diocese then by city or village.
