Martha,
There were just three Legier's in all of Ireland as shown in Griffith's Valuation for Limerick in 1851. Details are as follows....
Catherine Legier, Civil Parish of Kilcolman, Townland of Drominaclara.
Eliza Legier, Civil Parish of Iveruss, Townland of Beagh.
William Legier, Civil Parish of Iveruss, Townland of Beagh.
Hope this helps.
John...Sydney
