I am sorry to report that Amazon finally told me after almost a year that the manuscript containg the 1722 immigration record for Matthew Acheson & family is not currently available through them.My next step is the LDS library.I know this record is available without having to go to the National Archives, because it was in print.
When you mentioned the 1912 information, were you referring to the "History of the Achesons in America," by Rev. John Leon Acheson?He was my grand uncle, and he died in Pittsburg, PA. He was born in Oregon where most of his extended family is buried.I have a copy of his manuscript, except for the lost section containing the decendency chart.John used his considerable influence researching the family roots for several years.
I have been able to answer two of the three significant questions he posed.The remaining question was regarding the dual generations of Mathew/John in Little Britain, Lancaster Co., PA.The 1722 immigration record should provide additional proof that the conventional wisdom about there being only one Mathew, the son of John Atchison(b.1710) is incorrect.The ages of the Mathew/Matthews don't work chronologically.The other proofs are the Beers portrait of the Matthew Acheson family, and the Lancaster tax records that shows the next door neighbor of John was Mathew Acheson, and shows further that the Widow Acheson moved in with Mathew's family after John Atchison's death.The sons of John Atchison had much earlier moved to Colonial, SW Pennsyvania along with represenatives of the Cherrys, McDonalds, Reeds, etc.
When I get the 1722 info, I will let you know Kristina!
