That is interesting... My great grandfather was also in a soldier. He also took the name Appel. He served for over 30 years when he came to this country in 1890. His name was Peter Appel, or Petter Gustavson. He was born in Voxtorp in Jönköpings Lan. He served in Gimmarp in Jonkopings Lan. It is near Gallaryd. Growing up an Appel we through it had to do with the fruit tree. Wondering where you Appel served in Sweden?
