Please see my previous message this date. I think one twin was named after Oliver, who was either a cousin or brother to Thomas B. Guppy.The second twin was Samuel. Oliver's father was named Samuel but I do not know if Thomas B. was also Samuel's son.I have found no information listing Thomas B'sbirth or his being in Samuels's household or any listing of his being a son of Samuel. It would be interesting to view his death record in Concord NH,as his parents and spouse may be listed there. Also, I believe Thomas B. Guppy may have died around this time.
