I hate ignoring unanswered posts, but I can see why this one hasn't been flooded with responses, there are no easy answers. I just tried looking at Dumfriesshire graveyard listings on line, but the only one I could find for Kirkpatrick Fleming is showing much earlier dates than you want, mainly pre-1855.
It may be that your first death, in 1895, has a stone in Kirkpatrick Fleming Churchyard but I suspect to be sure you need someone in the area to take a look for you.
As to your second, that's (in terms of family history) relatively recent. Have you tried contacting Dumfrieshire Council to see if they have any cemetery records from that time?
