Hi:
You might be interested in the following Household Return for the 1901 Census. It lists a Mary Howard aged 70 who was a mother-in-law.

There was another Howard family also living next door in this townland. Liskennee was a place name in Ballyblood.
Are you aware of the Historic Graves website? We were trained by them 6 years ago to record the graveyards. Here is the listing for the Howard family:

There are 3 other headstones associated with the Howard family in the old section of the graveyard. In addition, there is a burial register for Tulla that starts in 1917.
Let me know if you need further information.
