The name you suggest is highly questionable.
I will be very surprised if it exists as is. There is no Greek word starting with "Pastri".

If I had to guess, I will go for Patrikakis, a modification of the word "Patrikios".

Pastdekakis is also a fictitious name. "Past" is past, is English.
If the text is Greek ask somebody who speaks Greek to read it for you.
