I started out as a volunteer, just like you mentioned, wanting to add my family that I had researched from Ancestry records and my own relatives.
I was hoping to connect with ancestors from Ireland. Then interesting discoveries came about, I was not from Ireland at all, but from France and my relatives came and settled in Canada before coming to New England, in the United States.
But after my years on WikiTree and helping others research and finding more discoveries I feel I am a genealogist. Just like joining the military, they call you a soldier, or marine etc but you have to have training. I think WikiTree offers that "hands on training" and helps make us Genealogists in our own right. Thanks WikiTree and your volunteers and their expertise and willingness to go out of their way to help others!!!
