UPDATED 10/7/2017
If you or one of your Kerry parents has the surname Brennan, an autosomal DNA test kit has been donated to assist those researching their Kerry Brennan ancestry. Please leave a comment below and I will get back to you.

In 1901, 563 Kerry people bore the Brennan family name.
97 households had a Brennan listed as the Head of Household.
​Brennan households are listed by townland & DED as spelled in the 1901 Census in alphabetical order. In some cases I have added information in the index below which may help you to more easily identify your ancestor, for example if they were not born in Kerry, had an unusual occupation or religion.
Whilst every effort has been made to ensure the accuracy of this piece of research mistakes may have occurred. If you are aware of any or have more information to add please let me know in the comments box below. Please include online links. This is a work in progress and will be updated as I have further information!

I recently discovered a genetic cousin via Autosomal DNA testing whose Irish roots are in the name Gahan. My genetic cousin could be related to me on my maternal side but since we have to start somewhere I did a search of Brennan/Gahan marriages 1790-1863 on rootsireland.ie. (Civil Registration began in Ireland for Roman Catholics in 1864)
1790 Sept 19 Mooncoin Kilkenny John Gahan of Farrensarron Margaret Brennan of Farrensarron Wit. William Henebry & Richard Walsh & Thomas Dunphy

Note; since Celia is an uncommon name I searched for a Celia Brennan born in Kilronan. Found Celia born to Michael Brennan (could he be Mary Brennan's brother??) & Margaret Cooper 1840 Dec 28 ~~also Sara b 1835, Guy b 1837, Margaret b1847

Gaylord V Brennan was born in Illinois in 1922. He was the son of Louis G & Edna A Brennan. In 1930, the family were living in Rockford, Winnebago, Illinois. Both Louis George and Edna were born in Illinois. By 1940 Edna was widowed and she and Gaylord were lodging in the home of Herbert and Ada Cook in North Court Street, Rockford. 
A Draft Registration Card for George Louis Brennan 1918 suggests that Louis/George  used both his first names interchangeably at different times in his life. His wife is named Edna and he is recorded as self-employed with a peanut vending machine business. George is recorded as 5 foot 10 & one eight inches tall, of stout build with blue eyes and sandy hair.
Louis died on July 29, 1935 according to a transcription of the Illinois, Deaths and Stillbirths Index 1916-1947. This record also tells us that Louis was born on Feb. 22 1880 in Shirland, Illinois. He was only 55 years at the time of his death.
This record of Louis' place of birth gives us a great clue for checking the 1880 US Federal Census, if he was born prior to the census. Imagine my delight when I found Louie aged 3 months living with his parents Martn & Marccella Brennan. Martin was born in Wisconsin and Marcella in New York. All 4 of their parents were born in Ireland!
​The transcription of the Illinois, Deaths and Stillbirths Index 1916-1947 came to my aid again giving me the death of Martin C Brennan (birthplace Footville, Wisconsin) on March 21 1933 in Rockford, Winnebago. Husband of Marsella. Martin's father was John Brennan and his mother Mary Cannon, both of whom were born in Ireland.

Pilot Officer Ian Eric (“Doggie”[1]) BrennanPilot Officer Ian Eric Brennan of 3 Squadron RAF Volunteer Reserve was tragically killed whilst conducting dog fight training in his Hawker Hurricane on 1st March 1941. He was aged 22 years and 9 months when he was in collision with the Hurricane of Sgt Joyce.
P/O Ian Eric Brennan flying Hurricane V7069 was the senior pilot that day, and Sgt Joyce in P3255 was the pupil hoping to gain some fighter tactic experience.  Out off the Sumburgh Head a number of maneuvers had been carried out and all seem to go OK when suddenly the two aircraft collided and unable to recover P/O Brennan’s Hurricane plunged into the sea. The other Hurricane, severely damaged and with its pilot Sgt Joyce badly shaken up managed to limp back to Sumburgh where he got down safely, alas his instructor P/O Brennan, aged 22 from Farnborough, Kent, was killed and his body never recovered[2].
His plane was recorded as crashing here: 59.916739, -1.166665[3]

The 1911 Census gives us a wonderful picture of my Gilleran great and great great grandparents.
My great grandparents, Michael Gilleran and Ellen Beirne and their five children were living with Michael's parents, John Gilleran and Anne Fox. 
John Gilleran of Roadwalk and Anne Fox of Clooncraff (age 18)  married in Roscommon RC Church in 1872. The Civil registration record gives only their fathers' names but the Church marriage record transcription (rootsireland) records the following;
Parents of John Gilleran, Patrick Gilleran and Mary Hanly
Parents of Anne Fox, Michael Fox and Margaret Brennan .
John Gilleran was baptised on Feb. 28 1845. His godparents were James Hambrogue and Margaret Brennan. (rootsireland) I have found baptisms for 6 siblings,
Thomas 1833
Patrick 1835
Margaret 1837
James 1840
Michael 1842
William 1847
John Gilleran died in 1920, in the company of his daughter-in-law Ellen.

The 1911 Census gives Anne Fox Gilleran as the mother of 4 children. Baptism record transcripts give us;
Mary Ann born 1873
Michael born 1874
Mary Ann born 1875
Patrick born 1877.
Anne died in 1925 of old age (75 acc. to the Death Record) in the company of her daughter-in-law Ellen.

Ellen Beirne Gilleran was the daughter of Malachy Beirne of Ballyglass, Rahara, Co. Roscommon & Ann Donnelly.
In 1857, Griffith's Valuation records Malachi Byrne as a tenant of Robert H Gunning in Ballyglass, Rahara.
Malachy Byrne married Ann Donnelly in 1854 in Knockcroghery.
Patrick 1855
Brigid 1864
Martin 1867
Timothy 1870 
Ellen & Margaret her twin were born in 1873.

​In 1920, Dave Branon and his wife Mamie were living in Fork, Lexington with their 2 year old daughter Viola. Both Dave and his wife could read and write though neither had attended school. Their home was rented and they both 'worked out' as farm labourers. 
On June 16th, 1920, Dave and Mammie's lives  were struck with immeasureable grief when their daughters Ethel and Edna died only 3 weeks after birth. There was no physician present at their deaths so there is no cause of death recorded. In their death certficates we discover that Mammie's name was Mary Martin and that she and Dave were born in Lexington County. Ethel and Edna were buried in St. Paul's Church on June 17th, 1920. The certificate does not identify if this was the Baptist Church or the Wesleyan Church.

By 1940, the family had grown to include Dave Junior age 20, Wade age 18, James T age 10, Martha age 8, Mayole age 6 and Swanee, Dave's wife, age 17.
