Somewhere around 1975 my grandmother, Cora Larson Witt, showed me a genealogy of her ancestors  that was written by her father some years earlier.  The handwritten pages showed her lineage back  to 1500.  I became fascinated with genealogy then and have been hooked ever since.  I have made  plenty of mistakes in my research, there is still data in my tree that is not sourced but I am  working on filling in those blanks.  I learned that you cannot necessarily believe the family  trees that are found on line.  I had an error in my line that connected me to the Mayflower.  The  error is repeated in numerous trees found on the Internet but there is no evidence for a critical  marriage in the line.  Be careful with what you copy from others.  Make notes of anything that is  not proven.  Enjoy your search and I hope there is some bit of information I have posted here  that may help you find more about your roots.
