My Grandfather was a Mason and my Grandmother very active in the OES. The thing is, he never mentioned it other than talking about the Band he was in in Grotto and how important it was that I should learn to play an instrument. My Dad was not a Mason, nor was my Uncle, and I am not sure why.
It was alsways in the back of my head to find out more about it, but getting married, having kids, etc did't leave the time.
When I mentioned to my Wife I was thinking about looking into it afer out youngest graduated from HS she supported it entusiastically. She acually asked a bunch of questions and really engaged with the member of the Investigating Committee. It was only a couple month after I was Raised that she joined the OES Chapter near where we live.
Our Son if VERY interested in joining, but works 2nd shift at this time, so he will have to wait until a slot open up on 1st shift that he can fill before pursuing it. My one Son-In-Law was super interested, until I took him to visit the Lodge near where he lives (He and my Daughter live 3 hrs away from us, but Still in PA.) Unfortunatly while the WM there was very entusiastic, not one other Brother came and introduced themselves to us during the meal, which was a very lackluster effort. My SIL went home after the meal and I went to Lodge. Sadly only myself and one other Brother were on the Sidelines as everyone else in attendance had to be shuffled into a Chair. The meeting was also 90% business and only 10% "Masonic Content" and the folks who were dragooned into sitting in chairs had little idea of what they were doing. You would think a Lodge which was that short of active Members would be entusiastic about someone showing up looking into joining. Afterwards, no one from the Lodge ever contacted my SIL, even though the Secretary gathered his contact information. So in this case first hand experience soured him on Freemasonry.
