Specialisms? None really. Just 30 years experience in researching my own family and my wife's and helping a few friends with theirs.
My wife says I have OCD. I am pedantic about recording my sources and keeping records generally. Last year she thought I'd really gone over the top when I created an index of all my field books. She gets very envious now when I can turn up some notes I made ten years ago and she can't find what she wrote last week. But she won't let me create an index for her -- says she couldn't do with all that order!!
As for being here -- this is a wonderful and well-ordered site with great people doing the same as me, just researching their own family history and trying to help others along the way. Like many here, I have migrated from elsewhere.
All the best,
