If you will go to the Marion Co AR web page argenweb/marion you will find the full story regarding cemeteries that were removed before Bull Shoals Dam was built across White River ca 1950. You will also learn where those cemeteries that were removed were located originally and where they were moved to. A link is being created from the Marion Co page directly to Find-a-Grave etc from this page. It may not be completed as yet, though.
"The Old Trimble Cemetery was located 8 1/4 miles north of Peel, Marion Co. AR on the Dean Farm. There was an unknown cemetery not far away on the upper corner of Section 17 on White River. This contained one mass grave of 13 remains. All were relocated to the New Peel Cemetery." Quoted from: Cemeteries of Marion Co AR 2008 by Vicki Roberts.
