Thanks for your email - very much appreciated.
If you've access to Genes Reunited then you'll find my tree there.
Basically my Bonnell ancestry is as follows:-
3G grandmother: JANE BONNELL. Born Pembrey 1795.
4G grandfather: DAVID BONNELL. Born Pembrey c1750, died Pembrey 1820. Buried Pembrey Parish Church.
5G grandfather: WILLIAM BONNELL. 1702 - 1775. No further details.
6G grandfather: WILLIAM BONNELL. c1680 - 1756. No further details.
7G grandfather: RICHARD BONNELL. c1650 - 1716, No further details.
Would be very interested to know whether any of the above appear in your tree.
Through Genes Reunited I've made contact with four or five previously unknown distant cousins, all of whom have Bonnell ancestry.
