PIERCE or PEIRCE Frank, s. of James and Lois-R., [born] Jan. 27, 1848.
↑ Frank's birth is so long after either of the other two known children that one doubts he belongs to this family, but the "Lois-R" as mother strongly argues he does. If so, it also seems probable that he died very soon, as no sign of Frank is found in the 1850 census. Brother Arba is living with his mother (1850 census, lines 2-3), while brother Watson is living with his uncle (his mother's brother Phineas Whitney Reed, [1850 census], Watson is line 9). Uncertainty is caused by the absence of a death date for the father, since obviously if the father died before 1848, Frank cannot belong. The father has not been found in the 1850 census either (at least, he's not at home - since he has not been identified yet, it is hard to put together an effective search).
