Greetings, I have been reading Indians of Southern Maryland
( A fantastic piece of major research on an under- documented part of American history.)

I am curious about some of the locations noted in the book, specifically old plat or tracts. As you know, sometimes historians plat out the boundaries to reveal the tract shape. More recently they show that shape on modern aerials.

Has any researcher completed any of this kind of mapping project for PG county? For instance a man named George Horvath platted out old farm boundaries in Carroll and North Baltimore Counties, but I know not a lot of this kind of research has been done statewide because it is very arduous work !

Thanks for any help you can provide. Regards, Kimberly Abe
