Seems to be a million spellings for this name.I have some Wallihan, Wellihan, Wollenham - but I think they are all the same family. I descend: JOHN WALLIHAN B. abt. 1740 in Ireland Came to America. May have settled in Georgetown, Washington, DC Then traveled into Maryland,Pennsylvania, and Ohio. Two of his children married into the Rogers family. Catherine Wollenham 1779-1851 M. Alexander Rogers 1773-1843. Their daughter, Nancy married Dr. Levi Wilcox, Jr. 1797-1851. Does anyone recognize these people?
