Hey! Wow - I don't know how I missed this. This is him again.
This lists Michael Borkovich (Miho Borkovic) of Etna as his uncle. I had assumed that Michael and Nick were brothers.
My Anton Borkovic has several documents which list that his father was Gjuro. So - according to this, Anton and Nick were brothers, and Michael was their uncle. Michael was the best man at Anton's wedding in 1898.
I have seen the Orljakovo/Kamanje location before. Miro Caic posted this several years ago:
http://feefhs.org/links/croatia/kamanje.htmlThe problem with Kamanje records is that Familysearch only has records through 1857. I just emailed Sanja to see if she is aware of what Kamanje records might be available at the state archives.
