Here is that Mary Morrison’s birth with mother Honor Kevil.

I thought it so good but then there is the census records in Carrownacreevy 
I've been looking at birth registrations for children of Michael Morrison & Honor (Kevil) and at 1901 census.
Birth registrations of siblings of that Mary Morrison include Honor 1870 and Margaret 1873.
Possible relevant death registrations:
1902 Michael age 85 informant Catherine Morrison, daughter
1907 Honor aged 33, informant Catherine Morrison, sister
1918 Honoria aged 88, informant Catherine Morrison daughter
All registered Ballymote, Sligo
I couldn't decipher residence on the birth and death registrations. It began with C.
All the above names were on the 1901 census return for household of Michael Morrison & wife Hanoria at Carrownacreevy.
Michael Morrison age 72
Hanoria 70
Catherine 35
Mary 26
Hanoria 24
Maggie 22
Michael O'Connor age 18 grandson
If it was the family of Michael Morrison and Honor Kevil, ages of daughters were a few years off. Mary should have been 33/4, Hanoria or Honor 30/1, Maggie 27/8. Birth order was correct. No birth registration in or anywhere near Sligo district for Catherine. She was probably born before civil birth registration.
