Florence's birth record is not in the Coventry town records. The birth record for sister Olive is also omitted. The record for Bertha was not added until 1943. However, I have made an assumption that these three sisters were born in Coventry, as were their older siblings.
Florence's death record at Coventry identifies her parents as William & Lenora.
In the Federal Census of 1910, Florence is age 13, living with her mother and two sisters in Coventry. It just so happens that they are living next door to Oscar & Anna Andrews, Aunt Velna's parents.
