Holly, Pfleger, Kamenice Bohemia ~1800

Hi All,
I suspect this is the story of my ancester Jacob Holly.
My Ancestor Jacoborz Holly was born in 1798 or 1801 in Kamenice, Bohemia. He became a baker and travelled to Hostow/Bohorodyczyn East Galicia where he married in 1829 and died in 1853.
His parents were also from Kamenice, Bohemia and were Francziszek Holly and Anna Pfleger / Flegerouz.
Would be interested in any advice on how I am able to ascertain which Kamenice in Bohemia my ancestors were from. There are quite a few I have found.
Thanks

Steve
