Should I give money for maintenance of a cemetary on farm owned by very wealthy cousin?

Cousin bought farm belonging to our parents; family cemetary has grandparents, great grandparents buried there. I don't plan to be buried there. Money to be put in some type of perpetual trust account to pay for mowing, etc. of cemetary. I make less than $32,000 per year and am near retirement. Farm owner is multimillionaire.
