I have noticed your message, logged more than 3 years ago, and presume you have since been able to track down your Lakin ancestors. Have you been able to prove that your ancestor Elizabeth Lakin was indeed a daughter of Benjamin and Mary Lakin of Tamworth? Online sources appear to indicate that Benjamin himself was baptised in the Cole Hill Presbyterian chapel, Tamworth, in 1735 Oct 19, the son of Thomas Lakin.
I have an ancestor Ann Lakin who was married in Nuneaton in 1796, and who may well be the daughter of Benjamin & Mary, baptised at the same Tamworth chapel in 1781. If that is so, and if indeed it was her aunt Mary who was married in 1747 to James Lakin of Hall End, Tamworth, then there is a remarkable link to my wife's ancestry: James's & Mary's son John Lakin was married at Shenston to Elizabeth Roby, the sister of John Roby of Alvecote Priory who is my wife's grandfather, three times removed.
I would be very interested to know if you have been able to trace Benjamin's ancestry. In any event, I would be grateful for particulars of his brother's, Thomas's, will of 1795 to enable me to obtain a copy: exact date of the will, date of probate (if known) and where proved (presumably in the Litchfield consistory court or a related peculiar).
