In fact this practice was so widespread in Darwen, and resulted in so many people who had the same odd names, that everyone was given a nickname, e.g.
Owd Timothy o' Timothys
Peg o' Bettys, Peg o' Titus, Ralph o'th'back o'th' heights
Jack of Ralph's Kay
Ealph o' Jack's Kay
Fish o' Fishes
and many more such completely useless identifiers!
