Hello William 1. Many thanks for your kind offer of help, unfortunately I do not have a plot or row number. I remember, as a very young child, being at a cemetery with my grandparents. I mentioned this to my late mum who told me that it would Arkleston Cemetery where her gran and Pop where buried. Mum died in March.
Is the cemetery run by Renfrew council? perhaps I could contact them for the plot location! Once again many thanks for your kind offer.
Joe
