Lodger,
Don't know if you can help but, the burial ground that I cannot find anywhere relates to Bellshill Relief Church.
After years of searching, I finally found all the baptisms for one family recorded at Bellshill Relief, between 1787 and 1802.
I know they lived elswhere in Lanarkshire at this time and assume that Bellshill Relief was their home parish church.
I also located burial records for the mother in 1831, Father in 1851 in the register
Second wife is not on the register but, her 1855 death certificate states she was buried in Bellshill Burying Ground.
I'm guessing that this burial ground has disappeared but, would you know where it was?
