Mothers and Fathers headstone

I’m rasing money on behalf of my partner who’s mother passed away in November 2016, she was buried along with his fathers ashes and unfourtunatley they still have no headstone. My partner left his job to care for his mum in the years before she passed and is still struggling now to get back on his feet as he is awaiting surgery himself and is unable to work. With rent arrears and debts and depression getting worse it’s killing him to not have a headstone at the grave. Any donation is hugely appreciated. He doesn’t know I’m doing this as he doesn’t like to feel like a ‘charity case’ but I know how much it would mean to him to get a headstone in place.
