Looking for info on the O'Flaherty's & the Prenderville's

Hello, I am looking for information on my ancestors. My mother, left front in the above photo taken around 1927 was born in Tralee.
Her parents, my grandparents, Timothy O'Flaherty (though he dropped the O' in later years) and Margaret Prenderville were married in 1910, according to 1911 census and had 13 children, though family memories only recalled 8 as survivors beyond childhood. Grandparents both died in 1973 and all but one uncle have now died also.
1911 census shows Timothy, aged 29 & Margaret, aged 23 residing at 3.2 Reidy's Lane with 3.1 being occupied by her family.
1901 census does not return Timothy of 19 years old at home, although the only 19 year old is listed as living with the Browne family at 32 Church St Listowel. He is shown as a farm labourer. My uncle always said the family had farming connections in the Ardfert area. One aunt said her Grandparents were Michael & Nora. She also talked of my Granfathers siblings, Nora, Hannah, Ellen & Minnie. These seem to check out in the 1911 census at 3 Ballybeg with head of household being Nora, a farmer (my Great Grandmother), formerly Honora Firzgerald. Checking birth records for her children reveals their father as Patrick O'Flaherty.
At this point I am a little unsure as the names do not fit perfectly with the family memories.
I think my first request is to confirm the whereabouts of Timothy in the 1901 census and also his birth which I have had trouble finding.
Thank you all in anticipation of any help however small you can give.
