Do You Review Your Conclusions?

The text that follows is part of ann 1826 deed that was transcribed and discussed in a recent issue of Casefile Clues.

[taken from Nicholas County, Kentucky, Deed  Book G: 560; FHL microfilm 252370.]
 
"...said Augusta Newman for and in consideration of One hundred and Twenty dollars in him [sic] paid by the said William Sledd, the receipt whereof is hereby acknowledged Hath granted bargained and sold and by these presents doth grant bargain sell alien and confirm unto the said William Sledd his heirs and assigns all the right title interest and claim he the said Augusta now hath as her [sic] of his father [sic] Thomas Sledd Decd in and to the tract of land said Thomas Sledd died seized and possessed of..."

When the deed says "his father" I originally assumed the reference was to Augusta Newman's father and that the deed simply left out the phrase "in-law" after the word "father." 

Now I am wondering if, when the deed says "his father," it is referring to William's father and not Augusta's father. 

Thomas was William's father and, while slightly odd, the reference would be correct.

How often do you review your conclusions?
