I found in the article "SURNAMES OF COUNTY WEXFORD" by Hilary Murphy the following statement:
"An occupational name surviving from the advent of the Anglo-Normans is Busher. It derives from the Old-French bushier (wood-monger) , and not le boucher (the butcher) as is sometimes stated. It appears in Latin as 'de Bosco', also as Boscher, Bosher and Bossher, in early records."
If anyone on this forum is connected to or researching any of these families, I would appreciate hearing from you. Thanks, Carl Boshers
