About the Project

The Hennigan Name Study project serves as a collaborative platform to collect information on the Hennigan name. The hope is that other researchers like you will join the study to help make it a valuable reference point for other genealogists who are researching or have an interest in the Hennigan name.

As a One Name Study, this project is not limited to persons who are related biologically. Individual studies can be used to branch out the research into specific methods and areas of interest, such as geographically (England Hennigans), by time period (18th Century Hennigans), or by topic (Hennigan DNA, Hennigan Occupations, Hennigan Statistics). These studies may also include a number of family branches which have no immediate link with each other. Some researchers may even be motivated to go beyond the profile identification and research stage to compile fully sourced, single-family histories of some of the families they discover through this name study project.

Research Pages

Here are some of the current research pages included in the study. I'll be working on them, and could use your help!

  • Hennegan of County Cork, Ireland
  • The Irish name Hennegan originally appeared in Gaelic as "O hEanain," or "O'hEanachain' but sometimes is an abbreviated form of the surname Henagahn. The surname Hennegan was first found in County Tipperary (Irish: Thiobraid Árann), established in the 13th century in South-central Ireland, in the province of Munster, and Offaly where they held a family seat from ancient times. Pronunciation, rather than spelling, guided scribes and church officials when recording names during the Middle Ages. This practice often resulted in one person's name being recorded under several different spellings.

Variants of the name Hennegan include O'Hannigan and Hanagan. This name in Irish is O'hAnnagain and the latter variants are the anglicized forms of this. The various spellings of the name that were found include; Hennigan, HENEGHAN, Heenan, Henaghan, Henehan, Heenon, Hanegan, Hannegan, Hanigan, Hannigan, Haneghan and many more.
