I have researched the family of my paternal great-grandfather Charles Kothsolkowski (aka Koski) going back to 1856 in London when he first married.I have quite a lot of names of descendents from both his marriages.Other than knowing that his father was Samuel or Shmuel and that the family possibly came from Sieradz in Poland before 1856, I have no other pre-1856 information.If anyone has Koski's or Kosky's on their trees and feel that there may be a link, please let me know as There are a few missing links here and there.
