John Brindley Esq from Coolagh, Nenagh, Tipperary

Hi,

My ancestor John Brindley (1810-1874) married in Templederry Mary Costello July 31st 1847.  

In the Griffith's valuation I can see him, his brother Samuel, and I presumed his father John Brindley Esq renting lands, houses, offices from Lord Donally and Reverend Dean. Coolagh, Kilmore, Sragh, Ballyquiveen, Ballincur. They were in grain milling industry.  

My question is:  What Esquire means back in that time?  Where and how did he  this received this title?  By his father, maybe?  Because there is also a Samuel Brindley and a Samuel Brindley Esq.  But how can i find how the father received this title? And as Esquire, did he have any responsibilities, duties to the Crown? And the responsibilities to the people they rent the land?

Is Lord Dunally and the Very Reverend Dean owned all those lands?
