TV host Sharon Osbourne's brother David Arden hopes to reunite the whole family for the sake of nephew Jack, who has multiple sclerosis.
Osbourne, 61, and Arden's relationship fell apart after a row over where their father Don should be buried, reported Daily Mirror.
"I'm the only other person in the family that has it - I know when I was first diagnosed I wanted to speak to fellow MS sufferers, I'm sure Jack feels the same. I'm not entirely sure what will happen, but before I die it would be wonderful to see the family back together again," he said.
Arden, 62, said his father's dying wish was to be buried next to his wife in Surrey but Don, who managed Ozzy's band Black Sabbath, was laid to rest near his mother in Manchester.
Arden is also battling with multiple sclerosis like his nephew.
"I am sick and tired of Sharon bad-mouthing our parents. It's really distressing. This has got to stop. I'm prepared to make peace with her for the sake of Jack. I'm battling the same illness and I want to try and be there for him," he added.
