Following the example of Michael Daly and Bridget Colbert as Ellen's parents I had a look at births of siblings.
You should be able to find others on the familysearch.org
but this is one on a CD between 1864-1875:

Bridget Daly born 1 Nov. 1870 #742 White Church, Waterford
#101218

No marriages as 1850's too early for Civil Records

This CD has the following -again no guarantees this is
your Gumbleton's. Parents James Gumbleton & Margaret Ahern

Eliza born 7 April 1865, #983 Killeagh Cork,Ireland #101108

Margaret born 24 Feb 1867 #1028 Killeagh #101148

John 29 June 1871 #955, Killeagh #255830

Maurice 1 Mar 1874 #1042 Killeagh # 255897

All these after 1864 you get copies of registrations from
the General Registration Office www.groireland.ie

There maybe other siblings as well as CD 1864-1875
