Interested in your Margaret Anne Ewing (m. Joseph F. Knapp). Do you know parent's names and if they might have been from the area of Duns, Berwickshire? Year of immigration? Other info? I have no direct connection to the Ewings but information might be helpful in backing into a solution for a Haig problem. There was an Isobella Ewing (b.c1760) married to a Thomas Haig (b.c1760) ... with a family of six ... who arrived in Northumberland County in 1834 (brig "Peace" via New York & Erie Canal)and there is some connection to the Haig family of Leeds County.
