There are only 16 people named DOODY on the 1901 Census in Co. Kildare -
LINKThis number was even less in 1911
Have you researched the families in detail with years
From what I can see Bridget DOODY was born c1845 in possibly Co. Kildare or Co. Laois
Her mother Catherine DOODY was shown on the 1875 and 1880 Brooklyn Census with her
George DOODY was shown as 33 in 1875 implying he was born in 1842
There is a record of a baptism on Nov 27 1842 in Stradbally Co. Laois -
LINKFather Matthew DOODY and mother Catherine MOON (also transcribed as MOORE)
Although the age is out, he seems to have died in 1900 -
LINKI cannot see more baptisms to this couple but there are more with the Father Matthew and Mother Catherine PHELAN
Margaret Jan 1839; Bridget Aug 1839, Maria 1848
Stradbally although in Co. Laois is just over the border from Kildare and not far from Athy to the west.
I didn't make the connection to Mary DOODY COPPERSMITH
In fact I can find little on anyone of this name
I can see she married Peter CAVANAGH and that he died c1887
She is on census returns up to 1920
I do not see a birth or arrival record for her
If you have anything else that might help someone here in Ireland make a connection especially in the more recent census returns you may more easily find relatives
Hope that this helps
