I've only recently come back to this family, but do recall finding nothing helpful in trade directories a couple of years back.
The name is Henry PENNISTON - at least it is in 1891 - it's a surname with umpteen variations

He was at 18 Charles Street, Huddersfield (RG12/3566/97/33) which I believe is now under a car park or similar.
This isn't my usual area of research, in fact I've never been there, but it's part of OH's paternal line and I've rather neglected it recently. If it turns out that Henry had his own shop, he'll be OH's first capitalist

(But if it turns that he stood in the rain hawking the local rag, we won't be surprised!)
