In order to put to rest some of the dialogue regarding first or Christian names, the Gaelic revival that took place in the late 1800's and early 1900's saw a return to fashion of many of the native Gaelic names that are drawn from the myths, legends and folklore of the Gaelic culture.
For example, the name of “Elizabeth” comes from the Hebrew and loosely means:
“…my God is satisfaction”.
By the way, Saint Elizabeth was mother of John the Baptist.
Eliza, Liz, Elsie and Elsa are among the many variants, but the Irish equivalent or translation would be: Eilís.
There was some explanation by a Jane Lyons in a 1999 journal called Breifne (Copyright, Jane Lyons, 1999) in an article edited by Brian De Breffny that those who are interested could look up. The URL for that article is:

Jane Lyons (who is very popular on these boards) raises the point that there was some differentiation of those children born of “Irish” parents and their protestant counterparts. Some of the favorite Irish Roman Catholic “Christian”, or first names, at that time for girls included:
Mary, Catherine, Bridget, Honora, Margaret, Ellen, Anastasia, Johanna, Judith, Julia, Rosanna, Maryanne, Elizabeth and Jane. Less common were the names of Magdalen Monica and Theresa. Marcella was found in Ireland but was rare in England.
Favorite Protestant girl’s names seem to have been:
Mary, Sarah, Elizabeth, Eleanor, Lucy, Catherine, Susanna, Hannah, Margaret, Jane, Isabella, Frances and Alice. Less frequently: Barbara, Gertrude, Dorothea, Charlotte, Diana, Rebecca, Lydia, Race, Phoebe, Henrietta, Lettice, Ursula, Penelope, Esther and Heather.
