The Hollabaugh Surname Project welcomes all who are interested in working together to find their common heritage through sharing of information and DNA testing. It appears from our genealogy research that Hollabaugh and its variants developed from the surname Hollenbach during the early settlement of the American Colonies. All variant spellings of either name are welcome. If your variation of the Surname is missing and should be included, please contact a project administrator and we'll be glad to add it to the list. All relations are welcome, male or female if you would like to join the group.
