Based on his Probate Calendar entry that Michael John Furlong located by 'Mallow Cork' was a Farmer. Best possibility on the 1911 census in this household, Michael J. with his wife Katherine M., and their children, everyone in the household born Co. Wexford.
@Ellen - did you order the birth cert mentioned in reply to your earlier topic ?
Michael's occupation on this, might help figure out why they were in Cork..
for reference - poss. siblings for Bertram found by Elwyn earlier :
Edith Amy Furlong Jan – Mar 1885 Vol 5, page 530;
Henry Ernest F Jul – Sep 1886 Vol 5 page 507;
Alfred Gordon F Jan – Mar 1890 Vol 5, page 479.
No sign of any of these on the Irish census returns that I could find
