Heraldry and a possible Coat of Arms is something I looked into possibly ten years ago. Whilst being 100% sure that the Henthorns do not have a Coat of Arms I thought it would be nice to have this in writing. I wrote to the College of Arms requesting a search and was prepared to pay of coarse. I don't expect anything for nothing but I was shocked at the price. I don't remember exactly but I think it was several hundred pounds (dollars)Much more than I was prepared to pay anyway.
