Hi obriain
These are my findings in 2008,using Griffiths Valuation of Ireland 1855 for the Townland of Whitegate. Website askabout ireland.com
There are no Egans listed there, but there are some in the adjoining Townlands. In Whitegate there is a Patrick Quinn as a tenant of Francis C Sampson M.D. leasing Houses & Land of about 1 acre& 5 acres, including Two Labourers Houses.
Then we have John Egan in Derrainy leasing from Roderick White a house,land & office on about 32 acres. In Cloonmohaun there is a John Egan leasing from Francis C Sampson M.D. & Wm. Blair a house & land of 1rood 15 perches. A Margaret Egan leasing from the same two men a house & land of 1rood 25 perches.
Then we have a James Egan in Cloonmohaun who seems to be in partnership with an Edward Murphy & Michael Hogan where they are leasing Houses,office & land of some 81 acres from Francis C Sampson MD and William Blair.
In Derrainy James Egan leasing from Roderick White a house & land on about 18 acres.
In Drummaana East James Egan owns a house,office & land on about 100 acres, plusanother house,office,land and six labourers houses and three gardens on about 182 acres.
In Drummaan South James Egan has leased to Francis C Sampson MD House,offices & land of about 181 acres.
I can't link them up to Daniel Egan but haven't been able to find any other records to search, so hope these may be of some assistance to you.
