I am afraid I am not going to be of much help but, I thought I might give you some information that may assist you in some small way.
I have checked a transcription of the Baptisms in CHART SUTTON and there is no record for any George Butler. However, I have set out below some Butler baptisms that might be of interest.
1788 Jan 12 William s/o George & Mary BUTLER private
1790 Jun 13 John s/o George & Mary BUTLER pauper
1791 Dec 18 Elizabeth d/o George & Mary BUTLER
1795 Jul 19 John s/o George & Mary BUTLER
Following these I found marriage as follows
1783 19 Aug George BUTLER Ba Bt M (Yeoman) Mary JOY Sp Chart L John Fuller John Pope
What happened between 1783 and 1788 and where is an obvious question? Alas, it is one to which, I have no answer.
There was also a baptism in Boughton Monchelsea for Jesse Butler on 11 Feb 1798 also with the parents named as George and Mary.
As a matter of interest do you have the Marriage Certificate of William BUTLER to Mary Ann KEDWALL? Hollingbourne District Dec 1838 5/383.
I also noted a marriage at MARDEN as follows
1811 May 14 George BUTLER to Mary SIMMONS w’s Wm Harris (P.C.) Tho Butler
The status of the Groom and Bride was not recorded on the transcription.
There is no record of a baptism for a Mary Simmons at Goudhurst in or around 1775. However, there is one for a Mary Hoath! Then a marriage and, another Goudhurst entry plus three records from HORSMONDEN as found on Family Search.as follows
1798 Jan 6 James SIMMONS Ba of Horsmonden Mary HOATH Sp Tp L W Manwring Jn Lingham
1798 Jun 4 Mary Ann d/o James & Mary SIMMONS
1800 Apr 13 James s/o James & Mary SIMMONS
1802 July 25 Elizabeth d/o of James & Mary SIMMONS
1802 Jun 15 James Simmons (Burial)
I hope this is not too messy and, sadly nothing concrete but, may be of use in elimination.
Happy hunting,
Tony
