Beaver County

Hello , my name is Roxanna Gwartney. I'm wanting to find out info. about a section in Beaver County. The section is 1-2n-21e. I was going threw paper work of my late Grandmother's. I found where checks were issued in 94'-97' on this section. I also got Increased well Density in 2005. Me and my two sisters are sole heirs to my Grandmother's estate, we recieved minerals in Beckham county, but this in Beaver county was not on Heirship. This is a Justin well. I need help in tracking down our ownership, could anyone help?? Thank-you.
