@eoe,
I understand and think you made the right decision, however it works out.
My mother and aunt were extremely estranged from their two brothers over something similar, which I'll not go into. I was on their side (mother and aunt) but got very sick of hearing about it in my teen/young adult years, while in a way it was the cause of their lives during those years. At some point not more than a couple of years before my mother and aunt began to "fail", I went to a family thing at the key estranged uncle's house. (My cousins and I vowed this estrangement stuff would never happen with us....) My point is, that my mother was glad to hear about her brother, or at least very curious, and was visibly glad the family break was healing --- all at the same time she was still pissed as all get out at the brother. One of her fondest memories, that I heard about for many years, was how the whole family used to got to the beach for picnics back in the twenties..
I still have the family letters, that I haven't looked at since I put them in order aroud 1980. Not all of them are about that, but a goodly packet are, and are rage filled. Next time I run across them (I still have a lot of notebooks from my design days, and that notebook is probably in with them), I'll toss the whole thing.
I did work out a family tree from what I could gather, and may save a few of the earlier letters pre The Mess.
I have four older cousins, two have died, one is getting way up there and I'm not in touch with and not estranged from, and one, now 82, is still sparky and writes me at least once a year and vice versa. I've two younger cousins - and we're older too, but not thaaaaaaaat old.
With the two younger (see first paragraph and our vow re estrangement) we all met this last year, but things are iffy between the two sisters and one of them, the least likely if you had asked us years ago, is a serious friend now. But, hey, at least we got together. I have no idea what caused cousin #1 to swear off the rest of the family, and no waaay we got into it at that lunch.
All by way of saying, your funeral may turn out like my lunch with two cousins - ok, all acting well.
Adds, you, eoe, might understand that cousin #2 and I went to the Irvine Museum to loll about looking at art after we left cousin #1 and her husband... a way of getting ourselves back from the stiffness. This 'luncheon' was good, or relatively good, but also sad.
