Shaw family Co. Cavan Co. Longford

[FLUFFY1234]

My great grandmother was Eliza/Elizabeth Shaw born about 1843 in Country Cavan her father was James Shaw 1808-1878.
I am trying to find Eliza’s mother was and did Elia have any siblings
Eliza married James Heuston in Co. Cavan and died in 1912 in Drumderg, Ballinalee, Co. Longford
Eliza and James had at least 4 children
Robert John 1867
Eliza 1869 died within a year, then Eliza Jane 1870 or are the 2 Eliza’s the same baby I don’t know,
Jane 1873
James 1874
All children seem to be born in Co. Antrim.
I am unsure on how or why the family came to be living in Co. Antrim.
So I’m interested in trying to fill some gaps on my ancestors.
Thank you for any help given.

Although Robert J is down as born in Co Antrim, he was born in Belfast (Ritchies Row, Ballymacarrett which is Co Down ).
