Burial site of John Henderson ?

[KAMA]

Hi, we are struggling to find where these ancestors are buried. Have spent a lot of time looking at local graves but have not managed to find them.

John Henderson born Torthorwald 1835 and died St Anns 17.6.1902.
His wife was Margaret Scott ( or Beck , she was illigitimate ) she was born abt 1835 and died in lockerbie 14 . 11. 1921.
And thei son:
William Henderson born lockerbie 1859, died 7.4.1938 at Applegarth.
His wife Elizabeth Patterson born about 1857 , died 11.2.1909 at kirkpatrick Juxta.
his second wife was Isabella Graham born about 1877, can't find her death.

Any help much appreciated.
