Thornborough Family History
Thornborough Name Meaning
from any of various places including Thornborough in Allerton Mauleverer (WR Yorks) Thornbrough in South Kilvington (NR Yorks) Thornbrough in Corbridge (Northumb) and Thornborough (Bucks). The WR Yorks and Northumb place-names derive from Old English þorn ‘thorn’ + burh ‘fortress’ or ‘manor’. The NR Yorks and Bucks place-names derive from Old English þorn + beorg ‘hill mound’ and would naturally also develop Middle English forms in -berry so it is unsurprising that the derived surname also developed to Thornberry or Thornbury as illustrated by Ellen
