Scrolling through the parish registers, I found this entry.
“Spurius” is probably another way of saying, “illegitimate.” The other big clue from this register is how his mother is enumerated; instead of listing a father first and then a mother, it’s, “Apollonia, filia defti Georgii Lekesch” – Apollonia, daughter of the late George Lekesch.
You are right. Spurius is the latin word for illegitimate. I have also seen this word a lot in my research, mostly in the older registers.
