Hi, Pat --

Available at Barnes & Noble, Amazon, etc. (Barnes & Noble offers member discount...)
It is also available online, in PDF format, at:http://onlinebooks.library.upenn.edu/webbin/book/lookupid?ke...

I'm sure this is where I found one bio on Lawrence, and a little on your grandfather, too.
