The Connells/ O'Connells of Bartibog and Douglasfield were probably not related unless it goes back a ways in Ireland. I think they are likely two different families by the time they came to NB. I have made two fairly extensive trees here on Ancestry for both families. I don't have the up to date info of the last few generations but I have a lot of the older/ early stuff. There you will find a fairly complete record of the original members of the two families and where many of them dispersed to. I could not find out what happened to a few of them so they either died in NB early on or moved away - most likely to Minnesota or Wisconsin. (1850’s-1880’s) or later on family members who left usually went to Boston or Maine.
