The next census substitute for Ireland are the Griffith
Valuation of 1850-52.
15 person's named Andrew Kennedy in North Tipperary
4 person's named Andrew Kennedy in South Tipperary
Andrew must of been a popular name.
A variety of Parish's for each.
Too many to be making any guesses, when did your Andrew
Kennedy leave Ireland?
Unable to find Tubberbrien in Griffith Valuations 'place names' in two resources. 1st. www.askaboutireland.iewww.leitrim-roscommon.com
third resource - no record
Tithes: Jubberbren, Tubberbrien - tried different spellings
in place names - still no record
This does not mean it didn't exist in 1829!
