Olaf Tengberg in on my family tree. We hired a professional genealogist a few years ago and he could not get back any further than His father ,Andreas Olofsson Tengberg b.5 Aug 1780 of Herrestad, Bohusland, Sweden...His mother's line goes back pretty far however.. 1618 -I am happy to share what i have and most of it is posted on my ancestry.com family tree-Robinson Family Tree. My cousin and I took a trip to Sweden and visited all of the places on the pedigree chart..took pictures etc...it was a life changing trip for me.
