I've never researched my genealogy, but my grandma did a long time ago, and has documents on it. Although I find it interesting to some degree, another part of me just can't be bothered to do all the searching or go to the expense. I find it more interesting to just hear stories about relatives from living family members. Any other back than that, and it is really just a bunch of names.
Bryony, for me it is like solving a puzzle and yes, it is just names, but the puzzle fits together and interlinks, and I find it fascinating. It has not cost me anything apart from some postage.
