You say you're from New Hampshire but South Berwick, as far as I know, is in Maine.
I was born and raised in Plaistow, mom was from Somersworth and my dad is from North Berwick.

As for where to start, read on these forums. Don't buy any eBooks (most of the information in them you can get for free in here). Read, read, read, read and then relax. When you think you know enough, start over.
