Nell, Thanks for the come-back. This stuff is like eating potato chips... hard to stop at one. I have been doing this research since 1960,plus or minus. Sometimes with year long respits. I used to travel a lot for business and found that I could do research as well as sit in bars and drink. I spent a lot of time in the Poughkeepsie area and would go to Vassar Library at night. They had a great history section with much to research. I think I learned a lot.
I searched the complete Surtees library and got a lot of good information. Then, in order to understand what I was reading I had to study history. I have read Stubbs and McCaully cover to cover. That helped. But, it's hard to keep all of this in mind while dealing with life as it comes.
Still, enough comes back when I need to evaluate new bits of info. Yet, I am always astonished to learn that much that I thought was original thought has been covered and rehashed.
