Marc, people make mistakes, no one is perfect, the better man admits they could be wrong, instead of bleating on about onosoddingmastic dictionaries.
The article clearly states that Johanus De Murgatroyd is mentioned as the constable of warley in 1371 (before 1379), back then people used the latinised form of their names in official documents in England, this gives it credibility if anything, the original document is in the local archives in the Halifax Town hall, you can contact the archive department and ask them http://www.calderdale.gov.uk/leisure/localhistory/index.html
,it is mentioned in many local history sources in addition this, so not crapola Mr Purile. And what has Gary Martin being a total unknown got to do with it? Does that discount him because 'MARC' hasn't heard of him. Local Historians know much more about their towns and villages than some Professor of History or Languages at Oxford, it's a case of 'Jack of all trades and master of non'.
I have personally been to the Murgatroyd house where the name started, it exists as a structure, I've seen it with my eyes and walked through it's doors.
Can you not understand that an academic in Oxford could sit mulling over the name Murgatroyd, never been anywhere near the source, never having read the documents and not understanding the regional dialect, suddenly comes to a plausible answer 'Margarets road or Margarets Royd'. He makes this mistake which is repeated by every other lazy sod thereafter. Meanwhile the real meaning is still known to the people who's dialect created the word.
Think of it this way: there are many margarets in the UK and have been throughout the last 800 years or so, why then is Murgatroyd so regionalised, why isn't there other place names throughout the UK, why isn't there more people called Murgatroyd evenly distributed throughout the land. I'll tell you why, it is because royd is a localised word pertaining to a few thousand acres of valleys in the Parish Of Halifax, set in the heart of the Pennines (Moors). This place is literally awash with Royds, they are everywhere and many of them backed on to the local moors, as the local Towmships used the Moors for common grazing and the royds for crops and were usually placed equi-distance from the valley bottoms and the hill tops. Some are named after men, waltroyd, some after nature akroyd or oakroyd and some after structures, brigroyd or Bridge royd.None are named after women, as back then property passed down the male line.
The key to this is the local dialect, around here coal was pronounce coil, hole became hoil, to rid something was to rode it which became royd over time. Moorgate would become Murgat.
Stop being to reliant on one source Marc and accept that you can't always be right. I stick by my initial statement, there are lots of mistakes on this site, mistakes based on assumptions made by academics. You, like a computer, just perpetuate the same mistakes. Free your mind, think for yourself and trust the tangible facts, rather than the hypothesis's of a distant academic.
