Orangefatcat,
I know you'd like more recent info, but FWIW [For What It's Worth]:
My perspective is getting to be a bit dated (5 years) and may be supplanted by more recent policy, but more latitude is allowed for contact with a DF'd relative, particularly a close relative, than for a non-related DF'd individual. Certain articles however, have made the point that "it might be possible to have almost no contact with a DF'd relative who doesn't live with [us]"
I know this was official policy up to the time of my leaving, but I've seen a bit of tightening up on this, from the exerpts of stuff that's been posted here on this website.
I'd like to point out also, Orangefatcat, that some Bodies of Elders are much more conservative than others on this issue, in my experience. It also depends on if a Witness who knows/observes of visits/contact being made with a DF'd relative raises a stink about it. But I've participated in correspondence with the Service Department over this issue (again, up to about 5 years ago), and this is the info I'm sharing. The point is much more latitude if it's a relative, particularly a close relative........Your mileage may vary.
[Edited to add: I double posted with others above and concur]
