An Analysis of the Brennan and Corcoran Families from Monasterredan, Lomcloon and Islands, County Sligo Ireland found in the Ballaghaderreen Church, Ireland Census, Griffith's Valuation and other Records

The Townland of Monasterredan (also known as Annaghbeg) is less than 2.5 km northwest of the Townland of Lomcloon in County Sligo and just over 7 km from Ballaghaderreen where the Cathedral of Ballaghaderreen was located. Ballaghaderreen Church records identified Corcoran and Brennan families in Monasterredan, Lomcloon as well as a frequent reference to "Islands" in connection with two Townlands. I think that "Island" could be referring to the Islands of Lough Gara, a large lake that is located primarily in County Sligo, but straddles the Roscommon border.

Please contact me if you feel your Brennan or Corcoran ancestors (or any of the surname variations) may have been from this Monasterredan area so that we can put the pieces of the puzzles together. It is clear after researching the Irish microfilm for several years that the vast majority of Irish families in the mid 19th century were large, often as many as 8-10 kids. Somewhere out there are descendents of our Irish ancestor's siblings researching their individual branch of the tree. Working together we will all get our trees back further!

Regarding the Griffith's Valuation for Monasterredan, Lomcloon (spelled Lomcloon in the Griffiths), and Islands: There was one Corcoran occupier in Monasterredan, Kilcolman Civil Parish, County Sligo: Patrick Corcoran holding 114 acres. There was a graveyard listed in that Townland as well. There were no Corcoran or Brennan occupiers in Lomcloon, Killaraght Civil Parish, County Sligo, but there were many Flannerys and Drury's.

The Mary Brennan/Edward Sherlock Family of Lumcloon. Special kudos to Jenny Brown, a descendent of this line who has extensively researched this family (she has a fabulously detailed family tree on ancestry.co.uk) and generously shared her findings with me. Here is a brief synopsis of the first generation of this tree:

Edward Sherlock was born in Lumcloon, Kilaraght, Sligo in 1844 to Mathew Sherlock and Mary Drury. His wife Mary Brennan was born in Lumcloon, Killaraght, Sligo in 1854 to Patrick Brennan and Mary Spellman and was baptized in Ballaghadarreen in April 1855. They remained in Lumcloom, Sligo until their deaths (Edward on February 29, 1914 and Mary on April 4, 1904). Edward and Mary had six children:

  1. Patrick James Sherlock migrated to Staveley, Derbyshire, England around 1896 and married Martha Bladen at the Church of the Annunciation in Chesterfield, Derbyshire on April 21, 1903. They had 13 children. He was a Coal Miner who remained in Staveley, Derbyshire, England until his death on July 15, 1960. He was buried at Staveley Cemetery.
  2. John Joseph Sherlock was born March 27, 1881 in Annaghmore, Sligo, Ireland. He immigrated to the U.S. sometime between 1902 and 1907, settled in Dover, Strafford, New Hampshire where he married Margaret Ann Mulligan on October 6, 1909. They had 10 children and the family resided in Dover, Stafford through at least 1930. They were residents of Boston, Suffolk, Massachusetts in 1940. John died in Boston, Middlesex, Massachusetts from Cancer of the Mouth on October 29, 1947 (and was a widoe at the time of his death). He was buried at St Mary's Cemetery, Dover, New Hampshire.
  3. Thomas Sherlock was born November 12, 1882 in Sligo, Ireland and baptized in Ballaghaderreen. He migrated to Staveley, Derbyshire, England with his brother Patrick working as a Filler in the Coal Mine. He married Alice Bate Brimelow in Chesterfield, Derbyshire, England on November 14, 1919. They had six children. He did July 8, 1963 in Chesterfield, Derbyshire, England and was buried in Staveley.
  4. Mathew Sherlock was born in early 1884 and baptized in Ballaghaderreen of February 3, 1884. He did not marry and remained in Lumcloon, Killaraght, Sligo throughout his life, and inherited the family farm when his father Edward died. He apparently suffered from epilepsy and died at the age of 55 in Lumcloon, Sligo in 1939.
  5. Peter Sherlock was born about 1886 in Ireland. He was living with his family in Lumcloon, Sligo when the 1901 Ireland Census was conducted. He died at the age of 18 in 1904 from a boating accident.
  6. Margaret Mary Sherlock was baptized on April 17, 1892 in Ballaghaderreen and was born earlier that year? in Lumcloon, Sligo. She immigrated to the U.S. at the age of 18 leaving via Queenstown Ireland, sailing on the Arabic May 6, 1914 enroute to Dover, Strafford, New Hampshire. She married William Ferguson Shayes in New York in 1922 at the age of 27. They remained in Syracuse, Onondaga, New York through at least 1940, had 4 children and moved westward to Los Angeles, California sometime before 1948. They remained there through at least 1954. Margaret died on March 28, 1967 in San Diego, California. Her husband William died a year prior in 1966.

This is a work in progress and will be added to over time as I uncover other records to add to this compilation.

I will present the Griffith's Valuation records at the beginning of this compilation as I am uncertain to which families they below due to the commonality of given names.
