This is what I have discovered through the online church records so far.
great grandmother
Elzabeth Dwyer Tonavane born August 4 1869
Parents James Dwyer and Mary Leyne/Leen/Lane acc. to 1911 Census married c.1870
Siblings
Helen Dwyer born Dec. 26 1862
Patrick Dwyer born Dec. 21 1866
James Dwyer born June 16 1872
Jeremiah Dwyer born July 1 1875
Mary Dwyer born Dec. 3 1877
Catherine Dwyer born July 8 1880
Patrick Dwyer April 28 1883
Did any of them go to America?
In the Irish Census 1911, only Jeremiah and Mary are still single and living at home. Mary Dwyer aged 76, my great great grandmother is now a widow. Her husband James died since the last Census in 1901. Mary is recorded as having 7 living children. Are you descended from Mary? If so I'd love to share notes on the family.
