Rebecca Parlin

I chose Rebecca's father to be Joseph instead of Gershom. Both were third generation Proctor's from Robert. Gershom's daughter Rebecca was born in 1733 which would make her 31 at the first born from the marriage with Oliver Parlin. Joseph's Rebecca was born in 1737 which would make her 27 for the first birth with Oliver Parlin. Rebecca of 1737 would make more sense although since all Proctor's are decended from Robert it may not matter which Rebecca it was. Both Rebecca's were second cousin's.

1733 Rebecca would have been 31 for the first child born and was 47 for the last child born (Gershom's Daughter)

1737 Rebecca would have been 27 for the first child born and was 43 for the last child born (Joseph's daughter)
