JH mark - Jean Florence Hamilton

Small cup with JH on the base. I've done a bit of research and I think this is Jean Florence Hamilton's Mark. Sometimes known as Jean Florence, also apparently has a jf incised mark. Worked around Stockport Cheshire 1978- 2000, now retired.
I've searched the marks book and matched the name from there.
I can't find a thread so thought I'd post in ID just so I could get the ok I've got it right

Not a mark I've come across before. I think the way the base has been cut, and mark points to a foreign potter. USA or Australia, possibly

Thanks for your reply Naomi...I've found a few other snippets of info since my first post, are you sure I can't convince you....



Here's another example of her mark:
