John McAdams, Jr. married Hester White in 1838 and was thereby entitled, as a married man and Head of Family, to an additional property grant from the Republic of Texas. His total "First Class Land Grant " was 4605 acres (One League plus One Labor). Since he had previously claimed a total of 3665 acres, this left 940 acres remaining to be claimed from his total Headright Grant.

On April 4, 1870, he was issued by the State a 138.3 acre tract of land in Walker County (Land Patent No. 155). This property is located about 3 ½ miles Northeast of the McAdams Pavilion location and he later sold his rights to the remaining 801.7 acres of his Headright Grant to James H. Starr on November 26, 1870.
