Yes, Tatjanu is the genitive form of the name
Tatjana in Croatian, Serbian and some other Slavic languages. I have never seen a male form of this name, so doubt it would have many hits on Google.
Could you give me the links you found so that I can be sure? The ones I found all refer to the genitive of Tatiana/Tatjana.
I also found that the male name
Tatianus is a form of a
Roman name
Tatius.
The only male Tatjanus I've found is a horse:
