Devlin / McClernon

Hi:  I am new to this site so please excuse any confusion I may have at the moment.  I recently joined this Ireland xo site and was given some really great news about possible roads to find my Irish roots.  I am looking for anyone that may have information on  Henry and Sarah Devlin.  Henry was born in 1836 and Sarah in 1816.  She married a Henry McClernon and Henry moved to the USA where he made harnesses in Iowa, married a Bridget Malone and had 3 children.  I am also trying to find Hugh and John who would be Sarah's children.  Sarah did immigrate to the USA after Henry's wife died and she was made guardian of his remaining two children Mary and Sarah.  I thought I would put out a message here since they very well could be from this Parish.  Thank you for your assistance.
