To me, you should know if they have one or not. From a legal standpoint I would think you should know. But, if it doesn't bother you to know or not, that's up to you. My step-dad had a over/under shotgun/.22 and a pellet gun. When I was a Sophomore in high school, I got a Daisy Pump BB rifle for a birthday. While in the Navy, got Small-Arms certified.
Don't worry! You are a family member and their mother. I just thought you would like to know. If you don't want to know and they don't offer to tell you, that's up to you and your kids. Sorry I said "legal standpoint". Perhaps Ken or someone else on the forum can explain better than I can why you should know or not know.
Ok. It's just never come up. Probably mentioned long ago but I have forgotten which child my husband gave one of his guns to (legally). It's not that they don't want to tell me, I just haven't asked...just always kind of assumed one or both had a gun. Neither is a hunter or gun enthusiast but would have one to protect family. I do know that the older grandsons are gun nuts (inherited from their grandpa ) they have air soft guns. And that's what was always on their Xmas wish list every year but they didn't get it til deemed old enough.
Basically, the only time our family knows about our firearms is when we post a photo of us on Facebook from the Range. For anyone on this Thread: One thing to really see is SASS (Single-Action Shooting Society) in action. When we lived in So. California, we go to Norco each year for the End of Trail Show. It was a weekend event held in a field. Talking about taking a person back to the Old West Days, WOW!! All the vendors dressed up in the era, gunfighters, real Indians. The Old Wild West came back to life!! Even met Hugh O'Brian, who played Wyatt Earp on the tv show, The Life and Legend of Wyatt Earp.
My grandsons love that kind of stuff...it's too bad that their grandpa died before most of them were even born... A major miss for all. The oldest was 5 when he died, his brother 6 months and the rest not even conceived for awhile.
One of my favorite places to visit in California was Bodie. I don't know if they've done more with it since but there were no facilities when I went there, other than a toilet, and it was on a road that was not well maintained at all, with very deep holes in the road. I liked it because many of the old buildings were still up, and you could walk into a very small portion of a silver mine before encountering a barricade, and it wasn't all touristy. There would be one park ranger there, but he usually stayed well away.
