Is there a 19th c. DECORATIVE painter named Henderson?

I found this tiny signature on a piano case:

I found out about the well-known Henderson artist clan:
http://en.wikipedia.org/wiki/Joseph_Henderson_(artist)

But I have not been able to find evidence of any Henderson who did decorative work specifically. Anyone know of such a Henderson? Or any other guesses on the signature? (It is VERY small, as you can see, so it is hard to know for sure what it says.)
