A big thank you, to the site, and to all those lovely people who answered my question. On the Web I have found the following:- http://inman.surnameweb.org/documents/nidderdale2.htm which indicates that Robert Duffeild made an attack on John Bayne of Riggs on the 25th May 1598, at Heslehurst, Bowthwaite. (Session Roll, see Yorks. Rec. Series). I have been researching my family tree for over 60 years and think I found Bowthwaite as being in the West Riding. There is a Latin record from the Session Rolls on the Web in the record series 03 york, which states 'apud Bowthwaite pd in West? Com pd in quodm loco ibm vocat Heslehurst in & sup etc. It is 60 years since I left school so my memory of Latin has rather faded. I gather it was written in the 6th year of the reign of Elizabeth I. My French is a little rusty too but I remember more of it than my Latin! >From the National Archives site I found:- Crown confirmation of grant of manors and lands in Yorkshire and Lancashire MD335/6/68/1 9 May 1538. Confirmaiton by Henry VIII to sir Arthur D'arcy, knight ............,rents and premises in Heslehurst, Waddington......Leeds.....With transcript of same, 19th century. I shall endeavour to follow the very helpful suggestions given. Lefayre.
