Well, again my sincere thanks to all of you lovely folks out there with your variant name offerings. I thought I would put them all together in the event it helps someone else to be JUST AS CONFUSED AS ME!! Is it any wonder I haven't found my poor dear Catherine Annie Gargan? Anyway, maybe this will eventually be the key, and I thought it was pretty interesting - hope you did too! And so, here is the final tally! The Growing List of Possible Gagan / Gargon Variants: arrigan, Gaughan and Gaughacan, Gavican, Cavagan, Gavican Gavikin, Gaviken, Gavikan and Gavaghan, Goggin, Gargen, Gargin, Gugin and Gugins Groghan or Grogan (possibly Gorman?) Gagin, Gorgan, Grogan, Gagen, Garahan, Garhan, Gaggin Garrigan, McGarrigan, McGahan, Hanafin, Hanifin, Hannafy, Hannifan Magauran, McGeoghegan/Geoghegan, MacArachian, MacGeargain, Goggin, Gargen, Gargin and Gargan and Gargon of course (confirmed as I have both on 2 different certificates for same.) And even a town/area in Co Armagh called Ballygargin? Regarding Gargan: Found mainly in County Cavan, Louth and Meath. MacGeargain (Gearg the old Irish word for Grouse, figuratively used for a warrier) is an old Breffney name. Regarding the Grogan possibilities: Grogan Irish: 1. Anglicized form of Gael. Ó Grúgáin 'descendant of Grúgán', a personal name from a dim. of grúg anger, fierceness. 2. Anglicized form of Gael. Ó Grúagáin 'descendant of Gruagán', a personal name from a dim. of gruag hair. the patr. form Mac Gruagáin (Anglicized McGrogan) is much rarer. Vars.: O'Grogaine, O'Growgane, Groggan, Groogan. Source: "A Dictionary of Surnames" written by Patrick Hanks and Flavia Hodges and published by Oxford University Press. GRUAGAN (gruag = "the hair"), meaning "the hairy man", anglicized GROGAN and GREGAN. He was son of Connor, who was the 156 monarch of Ireland; a quo O'CONNOR, of Moy Ith, Co. Donegal. A branch off the O'CAHAN of Londonderry pedigree. GROGAN, O' Growgane, O' Grogaine, Groogan, Grogan, Groggan - descendant of Gru(a)gán (diminitive of gruag, hair of the head or of grúg, fierceness, anger). A Roscommon name now found all over Ireland. Thanks so much everyone! Sharon
