I believe that your John was a bros. of my grt. grandfather, Jacob. Their parents: Jacob Wantz b. 2 Oct. 1771 d. 19 April 1835 who married 1796 Sarah Ringer b. 28 June 1780 d. 13 Nov. 1859. John b. 10 April 1814 d. 28 June 1877 m. 7 Jan. 1836 Sarah Juday b. 1814. They had the 7 children you named. I have children for Henry but only birth years for the others. A bros. of John and Jacob was Frederick b. 28 Feb. 1804 d. 10 Oct. 1875 m. Elizabeth Wolfe b. 17 July 1801 d. 7 April 1881. They had Irwin b. 1824/25 who married Mary ?. I have this family fairly well completed. Send your snail mail address via e-mail to me and I will send what you want. No one in this family could read or write until much later. The name is spelled Vance in official documents but Wantz or Vantz on tomb stones, etc. So, are we true Irish Vance or German?
