All information I have found on the internet show these details:
Abraham Birckhead Junior b. Oct 1671 d. 1750
M. ( 1st wife ) Abigail Evans unknowen dates
( widow ) ( 1st husband Edward Evans ) unknowen dates
M. ( 2nd wife ) Rebecca Billingsley on 18 Oct 1681 she was born 23 May 1677 and died 1745

Here is where I am getting confused,

If Abraham Jr was born in 1671 and his SECOND WIFE Rebecca was born in 1677 and they got married in 1681 this makes Abraham 10 years old and on his second marrage and Rebecca 4 years old.
HELP PLEASE !
