thank you for this, i was more looking into my grandfather's sisters and brothers my grandfther was Michael Joseph Sinnott born 27th September 1936, i have no idea where to get this information, I just know of 2 called Kathleen and Lily, i don't know if Lily was Lily or if she was named Angelina for instance...

Louise

Kathleen was registered as Catherine SINNOTT, mother maiden name DWYER

Lily is an alternative name for Elizabeth.  Elizabeth M birth was registered with mother maiden name DWYER.   

As both of these are likely to be still living I won't give further details.  The index details were found on Ancestry.   They are too recent for the full record to be on public view on the Irish Civil Records site.

In addition to these two and Michael, John SINNOTT and Annie DWYER also had four more children who died very young:  Denis, Mary, another Denis and his twin Margaret Anna.   You can view their death records on the Irish Civil Records site.  The deaths are in 1939, 1943, 1947 and 1947.
