The Devon Energy lease on my grandfather's land, of which I hold mineral rights (along with other relatives) is due to expire in May, 2011.  It is described as:

 110 acres, more or less, located in the Joel White Survey A-773 and the Lewis Watkins Survey A-808, and being more particularly described in a Deed from W.O. Keener et us to W.E. Holt, dated November 21, 1923 and recorded in Volume 121, Page 626, of the Deed Records, Shelby County, Texas.

 Can you tell me how I would find out if this was due to be renewed?

Thank you,

Miriam Kaye Fink
