George Solifelt(Alias Theodore Sullivan)--Book Mark Document

Looked at the Book Mark documents referenced in George Solifelt's Compiled Military Service Record and wanted to understand more about exactly what it was and why it was created.  I found an excellent article at https://twelvekey.files.wordpress.com/2014/10/ngsmagazine2015-01.pdf    
George had two alias that he used.  The information in his Book Mark file contains statements by others who knew him, and who gave sworn statements that George Solifelt & Theodore Sullivan were the same man. He also used the alias George Sullivan. One affidavit in particular contained some really interesting details.  It is a statement given by George Woomer.  

George Woomer said the following:   

I knew George H. Solifelt from his early youth.  We were boys together drove boat together on the Penns. Canal in the year 1862 and before.  in August of 1862 we left our Boats and went to Camp Curtin at Harrisburg PA and enlisted.  I enlisted in Co K 131st P.V. and he enlisted in Co H 126th Rgt P V. I saw him once in the service only.  it was after we went to the front.  Don't know the date but I know he serves in that company and regiment.  I did not then know he enlisted under the name of Theodore Sullivan--I have known him ever since and I know he is the same man who served in that Co. and Rgt.  I did not know he had served as Theodore Sullivan until he told me he gave as a reason for changing his name that he had been bound out when a boy.  I don't know whether he really knew what his name was or not.  I know his mother was Eliza Solifelt but I don't know who his Father was.

I located the FindAGrave entry for George Woomer & his wife.  Their grave is marked with a stone in First Methodist Cemetery, Lewistown, Mifflin County, Pennsylvania, USA.

There are 15 other documents within this Book Mark file.
