Looking for historical backdrop

Greetings from the U.S.

My gggrandmother, Johanna Bryan, married Michael Keating on 26 April 1822 at Kill, Rossmore.

They proceeded to have three children at Kill, County Waterford:

Catherine Keating 10 November 1823
Richard Keating 04 April 1826
Edmund Keating 14 October 1833

Their next child was born in Newtown, County Waterford

Johanna A. Keating 25 December 1838

The last child (that I could find) was born in Trinity Without, County Waterford

Mary Keating 22 July 1841

It just seems rather odd to me that this family would have moved around so much.

I cannot learn the father's occupation, other than from Johanna Keating's 1864 marriage certificate (in Cardiff, Wales, no less!) that her father was a tailor, now deceased.

Thoughts?
