1.) On "Gimme A Break", the police chief's wife and Nell Harper (Nell Carter) are longtime friends. While the two ladies are spending a pleasant day together, the chiel's wife confides to Nell she is dying - "it's terminal and there's nothing they can do" (I think it was a tumor of some sort) - and she makes Nell promise to make sure the girls are taken care of. The wife knows chief Carl won't be able to do it on his own and demands Nell promise to take care of the girls, who they have known all their lives and like very much.
2.) At least one of Maude's former husbands died on her. Another former husband died after they were divorced, and Maude accidentally flushes the ashes down the toilet. Her housekeeper, Mrs, Naugatuck is a widow. She keeps her the ashes of her husband, Cyril, with her - until Maude accidentally knocked the urn over. She vacuumed them up, conforting Mrs, Naugatuck the vacuum bag was recently changed.
3.) James Evans of Good Times was killed in a car crash after he got to the south to begin a new job.
4.) Lucy Carmichael, Lucy Carter and Lucy Barker are all widows. We know Lucy Barker (Life With Lucy) was married to Sam Barker, who owned M & B Hardware with Curtis McGibbon (Gale Gordon) The premiere episode explains that Sam left Lucy his interest in the hardware store. While she never cared about the store before, now she says she wants to be involved in the daily operations (hence the importing of pasta makers, an industrial strength fire extinguisher, and rearranging all the items in the store alphabetically.)
5.) Laverne DiFazio doesn't seem to miss her departed mom too much, nor does her father.
6.) George Jefferson commented how hard it was for Mother Jefferson to raise him all alone after his dad died while he was a little boy.
