Hello Thomas, RE: HENNEN - HENNAN - HENNING Family lines. From what I was told ( not documented ) the family was in Ireland but because it was so large and not enough land many families went to the different Bulcan Nations. My Gt. Gt. Grandfather was born in Germany or Prussia. I have no idea where his Father was born. I would like to see what you have if you would share it. Good hearing from you and Thanks. Have a Good Day, Leonard.
