57, and both LName and FName, but with a ‘twist’ on LNames. This twist on LNames has the goal of keeping each sibling grouped together with their kids and spouses in my contacts list, as follows…
I’m one of 5 siblings so to keep us in birth order the LNames are actually LName10, LName20, LName30, LName40, and LName50 (all with FNames, of course). And then the oldest sibling has 3 kids so they are LName11, LName12, and LName13. Next sibling has 1 kid who is LName21, next sibling has 2 kids who are LName31 and LName32…, and so on down the line. Spouses? The eldest’s 1st wife is LName19, and 2nd (and current) wife is LName18. The eldest’s 1st wife remarried, so she is LName19 NewLName — both LNames are listed.
When the second generation starts getting married and having kids they will be LName111 and LName112 for kids 1 and 2, and LName119 for first spouse, LName118 for second spouse, and so on.
It may sound more complicated than it really is. It’s not, and it keeps my contacts list nicely sorted for the families. I use this for some other families too.
