Searching for information on the surname Korcko or Korckova. Believed to be from Nizne Repase around 1891 and immigrated to US around 1905 (+/- 3 yrs). Two female Korckovas came to US however parents stayed in Nizne Repase. Any information concerning the surname Korcko or Korckova and Nizne Repase would be greatly appreciated. Thank you.
