There is a book that was published in the early 80's that lists almost the complete family tree from Leonard Shoun down to present time. I have found some errors in the dates and names of some of the families, but for the most part it is a good starting point. If you have not heard of this book please let me know and I can dig it out and send you the publisher and exact title. The baker family I beleive is listed in the book along with some references as to other books and resources. Hope this helps.
