I can tell you that the Etchells history goes back to the doomsday book,but more recently the area of cheadle/ cheadle hulme and chorlton was split between 3 brothers,hence the name cheadle Etchells.My Uncle was Jimmy Bowker,and whilst i dont know much of the Bowker history, they were Tobacco merchants in Burnley for nearly 200 years- this is well documented and i am sure you can reasearch this.
