You may not know that the 1911 Kerry census is now on line.
So I put in the name Shanahan from Tullamore and found one
large family, and another young girl staying with a family other than her own.Tullamore is near Ballylongford and Listowel,if you want to look at a map.
So to check the site,put in the surname ;Shanahan,
the Townland/Street;Tullamore, and the important one DED;
Shronowen.You will also have to put in Kerry of course.
Hope this gives you something. Angela from Kerry.
