Martha runs Maia's Books & etc. an online Family History book store that mostly displays at genealogy conferences but also has a brick and mortar store October through January in the Columbus Ohio area.
I brought home an American Family Paper Dolls: from the Pilgrim Period to the Civil War by Tom Tierney for my daughter this time. Martha has always had the best collection of family history items for children and I have bought many things for my family from Martha. Several years ago I bought the "Go Ask Your Grandparent" game from her as well as the "Family Lore Game." She has lots of great paper doll books and Memory Scrapbooks that are great for gifts.
She also has everything else under the sun genealogy. At FGS she has several of your core genealogy reference books, along with several Pennsylvania specific items. Take a look around Maia's Books. I'm sure you can find something to further your genealogy endeavors.
