Pearce from Cornwall?

[Rod In Sussex]

Can anyone give me some historical background on this.

When looking at a different set of relatives in Middlesex on the 1851 census, I noticed a number of Pearce names at Chiswick, who were fishermen (the Thames was still usable in those days!). My Grandmother was a Cornish Pearce who moved to London in the early 1900s, but there is no known link to these earlier Pearces.

Is there some historical tradition or link between the Cornish Pearce fishing families and those of Middlesex?
