I found the baptismal entry online for Andrej (1893) and also his brother Michael (1890) These records are from the area once known as Galicia, and are in Latin. The entries list parents names as well as grandparents names, and at far right in entry are the sponsors names.
Michael's entry has more information on grandparents names than Andrej's has, but the surnames are difficult to read
