My Gt grand father was St John Adcock born 1827 (died 1901, Dublin, Ireland) He married a Susan or Susanna Charlotte Kennedy in Dundalk, Co Louth, Ireland and had 10 children of which the eldest son was Robert James. Their 4th son was St. John Adcock , my grand father, educated in Dundalk and was in the Army, and died in WWI. I am George B St John (pronounced Sinjon) Thompson. I'm sure there must be a connection and would look forward to establishing it. Thanks to you, Roger for your info of Oct. last year as posted in Genforum.
