Panaretos - can you help.

I would appreciate hearing from anyone able to fill gaps in our Panaretos family tree which is slowly but surely growing. The following is what I already know:
Our great-grandmother: Panagiatitsa Panaretos, (b.1850 m. George E. Andronicos 1873)
Her father: Theodoros Vretos Panaretos (notos). from Potamos. Theodoros had two brothers (I think), Zacharis Vretos Panaretos (b.1836 Potamos m. Relia Stavros 1869) and Demetrios Vretos Panaretos m. Calliopi. Thank you.
