text: Possibly related to the Battle of Saintfield?

  But I'm not certain the plaque in that Wikipedia page's image is at this location. After a bit of online detective work, my hunch is that it's beside the Presbyterian graveyard in Saintfield itself. Specifically, in the centre of this image: https://www.google.co.uk/maps/@54.46244,-5.8327366,3a,15y,84.72h,82.96t/data=!3m8!1e1!3m6!1skaO6EE_ikLKSa574BbcWOA!2e0!5s20110901T000000!6shttps:%2F%2Fstreetviewpixels-pa.googleapis.com%2Fv1%2Fthumbnail%3Fcb_client%3Dmaps_sv.tactile%26w%3D900%26h%3D600%26pitch%3D7.03867578534728%26panoid%3DkaO6EE_ikLKSa574BbcWOA%26yaw%3D84.71861970715241!7i13312!8i6656?entry=ttu&g_ep=EgoyMDI2MDEyMS4wIKXMDSoKLDEwMDc5MjA3MUgBUAM%3D
  
  But it's a blurry image and just a hunch.
  
  So unless the original poster is able to respond on this note, I'd suggest closing it down.
