I am researching my 6X greatgrandfather Leonard Kretzer, I need the information for my DAR application.

I need help understanding the flow in his will, sale of his property and disbursement to his heirs.

I have the following information located on familysearch.
Leonard Kretzer died july 15, 1821 Washington County MD
Date of probate July 28, 1821
Book 6 page 139
Sale of PP book G page 197 ( I am unable to find)
First account book 6 page 216
Second/Last account book 7 page 273

Lastly on MDLANDREC
January 23, 1829
Deed KK page 516

My question is where would I find the distrubtion to the heirs. What website and what would the title of the record be?
