Anchors on hands are turning up quite a bit too.
Stupid question I know but I'm grabbing at any hint I can - do the tattoos or the the letters have any significance at all?
I really wouldn't know about the initials and so forth, Fran. But, the anchor stuff generally suggests a navel connection. Some sort of leaning towards the sea, at least.
That said; I wouldn't mind a £ for every black panther / tiger I've seen crawling up a blokes arm. Leaving its little red scratch marks ..... What in hell's That supposed to signify? See?
Sad and simple fact is that many basic tattoo designs were simply the in thing of their time. Fashions. And some of those fashions have endured for generations.
Dunno. The anchor design is something I was well used to seeing, around Portsmouth ~ Unsurprisingly

. Here in land locked Co. Leitrim though ....? Then again; Tattoo's are rare enough here.
Didn't ye mention Bristol in some earlier post(s)? I expect the 'Trade Mark' anchor would have been quite popular around there, in those days. Sea farer's thing.
