Typically having a settled family in this time frame would indicate this isn't a Romany Lock branch.
But with that said, what makes your Lock's so very interesting is the fact that Henry Lock married the Riley, and it appears Henry's daughters married Smith's.
So if we ignore the fact that they were settled and not traveling, just by looking at the surnames involved, at least suggests your Lock's could be Romany.

I think the law of averages gives your Henry Lock a better then average chance to be a Rom considering the connections to the Riley's and Smith's. That doesn't prove they are Rom, just suggests they could be.
