Great to hear from you. The names are ringing a bell with my husband as his fathers full name is Pieter Antonius Cornelus Teunissen (originally from Rotterdam) and Anton may have been a short form of Antonius.Names like that are traditionally passed down within the family and usually was an uncle or something like that.We are sending the information you have given us to my inlaws to try and work it out. I am also in contact with a women in USA that has the surname Teunissen and I am nearly sure she has mentioned Joseph. If it is the same person he may have been a twin, and his brother immigrated to USA. Leave it with me and I'll see what I can find out. Wouldn't it be fantastic to have relatives in Australia, Canada and USA as well as Holland!
Talk to you soon. Karen.
