FB O'Brien was a son of josephus and Amelia Upton O'Brien...born around 1869. Married MaryAnn Hammons and resided in Springdale, Fayette County for a time, we think he died in this area but no death record can be found. F.B. O'Brien had a grand daughter, Pearl O'Brien (my mother-in-law) and we want to find his gravestone. We have been to Springdale twice without any success..Any help would be most appreciated
