Surname Profiler indeed shows Roberts as Welsh, especially in North Wales. Miller is in the south and east of England, but is more common in central Scotland. It could have come from the German, Mueller, as often happened in the US.

There really is no substitute for the hard work of tracing one's ancestors backward in time via the paper trail, documenting them well one generation at a time, with one exception: DNA testing, which can sometimes be helpful.
