Luttrell

Looking for information on my relatives: Lutterell Family.  My ancestor, Richard Lutterell died in Dublin in January 1901 and lived at 2 Brunswich Villa in Dublin at the time of his death. At the time of his marriage to my great grandmother, Bridget Ellen Hughes, he lived 21 Aungier. His parents and sister, Alice, and brother, Edward, also lived in Dublin at the same address for a time.  They lived there at the time of their sons marriages.  Richard and his brother Edward (married to Mcentee) were married the same year, 1887.  The parents names were John Lutterell (spellings vary) and Margaret Byrne.  There is record of the family living in County Kilkenny.  There are records of John and Margaret's children's baptisms.  In addition to Richard, Clara RC parish, there is a Michael Luttrell born 1865 who was baptised in St. John's parish in Kilkenny city, and an Alice Luthrell, who shows up in 1862 in Co. Kilkenny. There is also a Joanna in Tiscoffin in 29 May 1869 and a Michael on 7 Nov 1865 in the same county. Parents are listed as John Luttrell/Lutral and mother as Margaret Byrne.

I would appreciate any direction for this family.  Where did the family originate?  Why did they move to Dublin?  Anything...Thank you.
