I just put in a photo request for a family member at Holy Cross and saw your open request. Wencelada was buried in this section: "F-08-011" (11th tombstone on the 8th row of Section F" according to my book "Cemetery Data of Nueces County"). I couldn't find any info on your great-grandpa William in my book. His name isn't listed at all as being buried at Holy Cross. Just wanted to share with you, you might already have this info.
