Have you contacted the Cemetery Office - they would know of any other BARR - of family connected burials there might be at Hoosier Community Centre.
If you are searching for other family members
Perhaps posting their names - and location if known - might prove helpful to you.
I see that you have submitted - 3 BARR burials - to the Find a Grave Site - online
