Thanks Lesley
That all fits in quite nicely really and could give the following sequence of events:-
c.1662 John APTOT m. Elizabeth nee ? @ Sussex?
1664 John APTOT s. of John & Elizabeth born
1668 Elizabeth APTOT d. of John & Elizabeth born
1670 Thomas APTOT s. of John & Elizabeth born
1671 Sarah APTOT d. of John & Elizabeth born
c. 1672 John APTOT & Elizabeth split
c. 1681 Elizabeth APTOT nee ? moves in with James TICEHURST
1683 James & John APTOT sons of Elizabeth APTOT nee? & James TICEHURST born
1688 Elizabeth TICEHURST d. James & Elizabeth born
1691 William TICEHURST s. James & Elizabeth born
Could this be a textbook case of Common Law marriage I wonder? i.e. one practice was that if a couple lived together for 7 years, and behaved as a married couple, then they were considered married with no need for a marriage ceremony. Of course, while John APTOT Snr was living then this could not have taken place, but what if he died somewhen imbetween 1683 and 1688. Elizabeth and James could be considered married if they had been living together long enough and this would explain why their last two children Elizabeth and William were baptised as TICEHURST and not APTOT.
Does this sound possible/likely?
