Hi. In reply to your inquiry regarding your G.grandfather.
I wold suspect he would be buried at Flanes cemetery, however the list shown does not show his name. However this does not mean he is not there. I have found that the lists shown are not alway accurate. We lived approx. 8-10 miles from that church. If I were you I would sent a letter to the church and find out who maintains the roster of buriels.
