This is a question really of statistics. What do you think the chances of two families with the same surname, born in Cambridge and Norfolk respectively are related? I have spent weeks trying to find a connection. I have a dna match via Ancestry to one family.
Do you think that it's a just coincidence of names?
Is there somewhere I can discover the frequency of the surname Mayes?
Thank you all.

Enter the surname on this forebears web page and it will show you the distribution in the UK - it certainly looks like an east Anglian surname.
https://forebears.io/This old website (below) giving information about Norfolk lists over 700 "Mayes" bmd's. However, due to spelling variants it's also listed as "Mase" and probably there are other spellings as well.
http://www.doun.org/transcriptions/surnames.php?letter=MMy grandfather was born in Cambridgeshire 1880s, in early 1900s he travelled up to Yorkshire for seasonal work. His parents were both born and bred in Norfolk but travelled down to Cambridgesire looking for work, where they settled and where all their children were born. On the other hand his father's oldest brother moved to the Midlands in the 1800s for work. In Norfolk the family surname was "Shearen"; this surname travelled to the Midlands but the dialect defeated the Cambridgeshire enumerator who heard "Sharring" and this eventually became "Shearing"
