I don't believe there is any TIME Limit on something like becoming a geneologist. There are different levels, such as from your contributions I see and would think of you as being a NEWBIE but maybe you are NOT....As for me, been doing this on and off since 2005 and being the only one in the family aside from one other cousin, I would Call myself the FAMILY Genealogist. Might even go as far as being intermediate, no longer a Newbie, but far from being advanced or Professional with all the creditionals and education.
So just continue doing your family line and soon enough, you will have others coming to you with question ...pace yourself, and take your time.....Genealogy is NEVER finished, it continues on ....
and welcom to our BIG FAMILY Marilyn
