My Davern is from Doon, Co. Limerick. John & Ally (FITZGERALD) DAVERN had Hanora (1853), Mary (1855), Jeremiah (1857), Ellen (1859) & Margaret (1862). I'm not sure if John died in Ireland or traveled to the USA with the rest of the family abt 1873. John may have had a brother James. Does this match any of your info?
