Our family is in search of a Marine named Charles Brock who was stationed in Samoa, island of Upolu during 1942-44. We have completed a DNA profile linking our father to the "Brock" surname. This post is on behalf of our father who is 67 yrs of age. We know that the American serviceman survived the war because our father continued to receive care packages up until 1950. The communication between our native grandmother and the American serviceman had also ceased by this time for reasons unknown.
