A bit of family info.
FIL isn't DH's real father. Him & MIL married when DH was 8. DH never knew his father.
Then when we got together DH told me he felt like crap coz of it, so I made a few calls & found his father for him. I was young & didn't think of the repercussions.

So anyway. He rang, DH talked to him. Then we find out why MIL hadn't seen or spoken to him in 18 years. Lets just say he wasn't a very nice person to DH or MIL. He actually threw DH up against a brick wall at 2 weeks old, so you get what I mean about not real nice.

Anyway, MIL freaked out, & FIL(step) thought he was gonna loose his boy. They have always been closer than any father/son I know.
We found out that DH had another brother & sister. He had 2 sisters but they tragically lost one of their DD's in a house fire at 12.

Anyway, we met them when DH was 19. I was 6 months pg with DD1. We spent 2 days with them, then never heard from them.
We sent them a card DD1's first christmas with our new phone number & I think DH rang them, but that was it. Nothing since.
We weren't too worried really, but over the years we have both been thinking about his brother & sister. We've never talked about them, but occasionally he's asked me to look them up on bebo & face book.

Well yesterday we found them. They don't know who we are just yet, well I don't think they've put 2 & 2 together yet, but they will.
We are happy to get to know them a bit, but we both agree that we don't want the kids knowing the situation & who they really are.
FIL(step) is their poppy. He's the best poppy you could ask for. I don't want them knowing anything different til they are old enough to handle it. Say, high school, or even older.

Plus I don't want him in & out of their lives. He doesn't have the best track record. From what we've seen & heard he is a different person & isn't that way anymore. I could tell from the way his kids were when we met them.
But thats not really the problem. I'm thinking of my kids & DH's family. MIL, FIL, BILs & SIL. I really don't even want them to know we are in contact in any way.

Do you think this is ok? Would you do the same? & how do you think I should tell them that I don't want the kids knowing??
