My Acheson line originally came from Scotland. ini 1604 they moved to Glassdrummond, county Armagh. they are directly related to the Gosford line (Sir Archibald Acheson). Patrick Acheson who was direct descendant of that Acheson line was a first cousin to our line.
If you visit my site at www.lcorrene.com/gene you will see my line (with some different spellings) and I am currently in the process of adding Patrick's line.If you can post your email address, or email me at lcorrene.com, I will send you a list of people I currently correspond with for this family. some of those may be able to help you as some of them are connected to different branches i.e. the Achesons of Grouse Lodge, Fermanagh & Donegal Ireland
