My grandfather was Joseph Jackson born 18/02/1893 in Park Lane, Oldbury, Worcestershire (then) England. He survived the Somme and Ypres, captured, escaped to Switzerland and married my grandmother Marthe Buser in 2 ceremonies in Lausanne and Bern on the 1st/3rd August 1918. Lucky me. His father was Joseph Jackson also and his mother Eliza Jane Elizabeth Knowles.Believe he had 2 sisters Emily and Matilda and a brother Henry. Any links?
