Mack, Duns, Berwick

[Mary G.]

My husband's 4G grandfather was a Peter Mack, who was married to an Isobel Brown, probably in the 1770's, so likely both were born in the 1750s. We have only found the names of two children, thus far - John, born in 1774, apparently in Duns, and sister Jean, born January 1778. John married Margaret Dale in 1809 in Longformacus, Berwick (children we know of include Peter, Isabella, Margaret, John, Alexander and Janet).

Would anyone have access to any information that might help find a marriage for Peter and Isobel, or the names of other children they may have had.
