The name of the transcriber was not specified, but the transcription is from Virginia Baldwin's Thomson Family web site, so I presume she is the transcriber.  I repost it here principally to help insure that it remains online and available (on the theory that two copies are safer than one).  If you are related to this family, you should definitely visit her site, which has much more information than mine.  (My interest is in the pre-1850 THOMPSONs of Christian/Todd Co., KY, so my interest in Asa's family is primarily focused on Asa's brother, John, and Asa's son, Roger, both of whom lived in Christian Co., KY.)

As is the case with most wills, it was written in one long, relentless paragraph.  I have broken it into smaller paragraphs for improved readability and, for the same reason, added some punctuation.  Names are boldfaced for quick searching.

Item I lend unto my beloved wife Dianna Thomson during her natural life three choice slaves, two choice horses, & my carriage & g (?) two thousand dollars in money & if she chooses to move to the Missouri to be carried there at the expence of my Estate or wheresoever she may chose to reside, and at her death the property loan to be divided in Eight equal parts and that my Executors pay to my daughter Polly Kirtley one Eighth part; to my son Roger Thomson one Do(llar); to Patsey Prewitt one do(llar); to my grand sons, sons of my son, John Thomson dec'd, one Do(llar) viz Pike William & John M.
