Do old English names look like Poythress, and which English counties should I search?

Research question: Do any medieval English place names or family records look like Poythress, and which English counties would a reader have to search to find them?

The only verified fact is an Oxford Dictionary of National Biography entry for Michael de Poynings or Ponyngs, second Baron Poynings (1317–1369) ¹. That entry gives the surname in two spellings, Poynings and Ponyngs, which shows that medieval spellings varied ¹. The facts do not mention Poythress or any name close to it, so they cannot confirm a resemblance ¹. The facts also do not name any English county, so they do not say where a reader should search ¹. The newest fact is from 2018, about eight years before October 2026 ¹.
