QUAID FAMILY OF CHARLOTTE COUNTY, NEW BRUNSWICK

I am looking for information on a Quaid family of Baille, Charlotte County, NB. I have a nice Civil War era picture of Mary and Eliza Quaid identified as William's sisters. The picture was in an album of Charlotte County, New Brunswick photos. The only William Quaid I can find who fits had a wife Eliza who died at 39yr-7mo-22dy at Baille and whose death was noticed in the St Andrews, NB Bay Pilot in July of 1883.Does anyone know anything of these Quaids? Thank you. Debbie
