Smith/Wilson Family

I have one more line in Enniskillen I hope to receive help on.  :)

Jane Roper (mentioned in the post before) married Thomas Wilson Smith.  Thomas was born 6/5/1837 in either Boho or Boe to James Smith, a shoemaker, and Barbara Wilson.  James and Barbara had two other children I know of - William (born 1833 in Drumconor) and Jane (born 1834 in Drumconor).  Thomas joined the military in 1855 and eventually moved to Paisley where he met & married Jane Roper and eventually died.

I have been trying to locate Barbara and James.  Recently, I located James' death cert w/ assistance.  He died on 4/3/1869 in the town of Enniskillen.  I have not been able to locate his final resting place or what happened to Barbara.  I assume she passed before 1864.  Any help locating their resting place and possibly their parents' information would be so much appreciated!
