I'm sorry to be off-topic but widows/ers just hurts my eyes. Why not use a more elegant alternative, widow(er)s? Even the uglier widow(s|ers) would be better.
BTW, shouldn’t “widower” be the person who died and the survivor be called “widowee”?
“Etymology Middle English widewer, alteration of wedow widow, widower, from Old English wuduwa widower; akin to Old English wuduwe widow”
It's one of these more universal words of Indo-European origin: https://ids.clld.org/parameters/2-770#2/14.4/149.7
