Where in the world do they come from? Following breadcrumbs.

My Leary and Callahan side is from Rathmore, Co. Kerry (and probably immigrated there in the 17th century from Cork). I can pinpoint the townland upon which they farmed in 1850. My Shea and Farrell line is from Limerick and lived in Mungret, near Limerick City before immigration. My Corbett and Grace line is from Turkstown, Co. Kilkenny. Thanks to finding their origen in Ireland I have been able to visit each place and in two cases stand on the land on which they lived. 

However my Bresnahan and Fleming side has eluded me. Unlike all three of the other lines there is no family oral tradition as to where in Ireland they lived. No vital record or obituary has been found that pinpoints the county in Ireland. So I started following the few bread crumbs I could see based on available records and a blanket search for other families with this surname in the immediate area.

Bresnahan is a traditional Kerry name. The names Bresnahan, Brosnan and Bresnan in Ireland are derived from the native Gaelic O'Brosnachain sept that was located in County Kerry in the South of the country. The name is most likely taken from the small townland of Brosna that is located in that region. A search of Irish parish records for the area - on line at www.irishgenealogy.ie has loads of Bresnahan/Brosnahan and other variants but none that fit my family. Sorting them out has gained me quite a collection of Bresnahans in this area of New Hampshire.Our family has used Bresnahan but others use Brosnahan, Brosnan.

Searching through the Bresnahans in Manchester and Concord NH where my ancestors settled opens up more questions than answers. James Leary, my great grandfather married Julia Bresnahan in St. Ann's parish, Manchester, NH in 1863. That points to her residence in that city since the custom was to marry in the bride's church.

A search for Bresnahan families in Manchester yielded many, some of which may be related. The best match for mine was Julia, 21with her mother Margaret Fleming 62, sister Honora 16 and two other perhaps related Bresnahan's Margaret  15, Patrick 17 and a Honora Dillon 19  in the 1860 census.  They all appear to be mill workers. A Margaret is listed in 1855/6 in the city directory and the family appears to have arrived (according to different census) between 1850-1855. By the date of this census Andrew Bresnahan, brother to Julia and Honora had already married Mary Leary sister of her future husband James. Perhaps that was how Julia and James met. Sadly I have been unable to find a record for Andrew, his wife Mary and son Corneilius b. 1856 in the 1860 census anywhere in the US. There is no death record for him in New Hampshire or neighboring states. Mary and her son disappear until 1870 when she is working as a servant in Concord with the woman who will marry the Patrick listed in this census. Her son is being cared for by his aunt and uncle James and Julia Leary.

From other records I was able to learn that the Margaret who lives with them in 1860 is the child of a John Bresnahan and a Johannah Fleming, Patrick is the son of a John Bresnahan and a Mary Fleming. I was led to these records by the obituary of Andrew's son Corneilius Bresnahan in 1903.  Margaret is listed as a relative of Corneilius when she attends his funeral in 1903 as is her half sister Julia. Both are listed under their married names and the marriage record of each showed they were Bresnahans. That led to a John Bresnahan who might be a brother to my great great grandfather Corneilius.

John Bresnahan b. 1810 lived in  Manchester NH with 1st  wife Johannah Fleming. He is father of Margaret Bresnahan who lived with our family in 1860 and of her half sister Julia Bresnahan with second wife Mary Sullivan Cashman. Margaret married  Peter Haggerty and Julia married to  John F. Cahill and both attended the funeral of Corneilius Bresnahan and are listed in obituary as relatives. Members of the Leary / Bresnahan family attended funerals from their family also and are identified as relatives.  Of course he may also be connected to our family via his wife, a Fleming like Margaret Fleming.

Since the Irish usually ask relatives to be godparents and marriage witnesses I explored a connection with the only Bresnahan family in Concord in the mid 19th century. I discovered that John Bresnahan whose first wife was Mary Fleming appears also to be the father of Patrick, the young man who lived with my family in Manchester in 1860. John Bresnahan is the godfather of my grandfather James T. Leary son of James and Julia. He is a good candidate to be related to our family, both from the association as a godfather and the surname of his first wife. He remarried twice after his wives died, to Johannah Coughlin with whom he had a second family and late in life to Mary O'Hara. Born around 1800 he is also of the right age to be a brother to my great great grandfather Corneilius, husband of Margaret Fleming. John's parents are Dennis Bresnahan and Mary Broderick.

Trying to research this John Bresnahan's orgin in Ireland was confusing. He might be from Cork (on his son's grave in Wolfboro, NH that is given as place of origen) or  Limerick. A Callaghan McCarthy is living with John in 1860. Callaghan  (from other sources and another researcher) is from Rathkeale in Limerick and with him is  his wife Margaret Bresnahan. Two other Bresnahan women live there Kate and Catherine both single and listed as aunts in the McCarthy family.  Are they from Limerick or from Kerry or from Cork????

The majority of the  Bresnahan families in Manchester NH are from Kerry especially the area around Castleisland and Tralee. However a search of the Kerry parish records, which are extant for dates  of the family births did not yield records for Julia or her sister Honora that fit.  From the map above it can be seen that Castleisland is very close to the border of Limerick and to that of Cork.

Cemetary records for Old St. Joseph cemetary in Manchester have many Bresnahan burials. Unfortunately no stone has the name of Margaret Fleming Bresnahan on it although she is most likely buried there. There is an old Bresnahan burial plot with multiple interments but no individual markers. 

So the mystery remains - where in Ireland did my Bresnahan great great grandparents Cornelius Bresnahan and wife Margaret Fleming originate?
