Not that I'm aware of. My father's family has had no interest in me since my dad was told he DAed decades ago - despite the fact that he's now back in.
My immediate family and my mother's extended family does not.
I've asked the folks in FS to please shun me and not disturb my Saturday mornings. The only time I've seen them in the past 3 years is a couple months back to invite me to the last supper (what I scary picture on the invite) - we'll see if they stay shooed away.
My heart goes out to you and your Uncle, Minimus.
