Hi Cathy,
Living in Nenagh, i know there are still Sheridan and Murray families in the area. But i researched your family history on the details you gave anyway.
In ' Irelands Births and Baptisms 1620-1881',
John Murry born on the 7th August, 1877 in Ballycarido, Co. Tipperary to John Murry and Mary Sheridan Murry.
Mary Murray born on the13th December, 1872 daughter of John Murray and Mary Sheridan.(this must be the daughter that became a nun).
Pat Murray born on the 20th March, 1879 in Ballycarido, Tipperary, father John Murray and mother Mary Sheridan Murray.
Tim Murray born on the 23rd February, 1881, birthplace Ballycarido,Tipperary to John Murray and Mary Murray Sheridan.
James Murry, Christening Place:Portroe, Tipperary, Birth Date:16th Sept. 1874, Birthplace:Portroe,Tipperary, Father's Name: John Murry Mother's Name: Mary Sheridan.
In the 'Ireland Calendar of Wills and Administrations 1858-1920':
Murray John: 13 April Administration of Estate of John Murray, late of Ballycarido, Portroe, Co. Tipperary, farmer who died 14th March, 1898, granted at Limerick to Mary Murray of Ballycarido, the Widow. Effects £49.
In the 'Ireland Valuation Office Books 1831-1856':
Land Assessment for John Murray in 1846, Youghalarra, Co. Tipperary.
In the 'Ireland Tithe Applotment Books 1814-1855':
John Murry, Tax Assessment, 1824, Youghalarra, Gurtnaveigh, Co. Tipperary.
In the 1901 Census I found a Margaret Murray living in Pallasmore, Youghalarra, age 60 (R.C.) Head of the Family. In the House at the time was a cousin Henry Murray , age 52 (R.C)
In the 1901 Census, Elizabeth Sheridan in the townland of Barbaha, Youghalarra, age 7, (R.C) living with her father William age 45 another daughter Mary age 5 and a son Patrick age 2 living in House 5 in Barbaha, I presume the motherwas deceased at this time. The mother does not appear in the 1911 Census eithier but the rest of the family does with occupations if you wish to look.
In the 'Ireland Births and Baptisms 1620-1881', you will find a number of 'Sheridans' in the Portroe area in the 1800's , i would say all the one family including a Catherine, Thomas, Marten, etc, check it out.
