Perhaps of interest to you, my great great grandmother, Annie Murray (Mrs. Patrick Wren) born c. 1828 parish of Bornacoola, Co. Leitrim Ireland. Was married and in NYC by 1850, where she died in 1901. In an affidavit, supporting the widow's pension application of her sister-in-law, Catherine Wren in 1891, she attests that Peter and Catherine Wren were married in NYC in December of 1853 by Fr. Patrick Hackett of Mobile, Alabama, who died there in 1860. She also attests that Fr. Hackett was her cousin and was visiting her in NY at the time of the wedding in 1853. (Annie parents were John Murray and Catherine Hackett). Don't know whether Fr. Hackett of MObile was connected to your Murrays or not but thought it might be of interest.
