Not in my newspaper (retired), Dave. I would be emending it to Hankses.
About 1 km down the road from me is the home and nursery business of Mr & Mrs Dilling. For years the sign at their gate has annoyed me by announcing The Dilling's.
Recently I met Mr Dilling and had the opportunity to ask about the sign. According to him, the signwriter had added the gratuitous apostrophe, and when Dilling pointed out the error, signwriter refused to emend it, so Dilling refused to pay. He reckoned that a free sign with a free apostrophe was better than paying the $300 of the signwriter's bill. He obviously doesn't care, because he could have painted out the apostrophe easily enough but has never bothered – despite many people querying it over the years. Some people are just cheap!
Two Dillings, two Hankses, two Millers, two Hayneses …
