My great-great-grandfather William Moore had been baptised in 1805 in Motcombe to William and Anna, making him the older brother of this John Moore, Methodist convert.
A little more digging in the fertile swathes of the internet led me to a detailed biographical article about Rev John Moore. Apparently he recorded the conversion event and stated it was "November 5, 1826, at half-past ten o'clock at night, while on my knees in the kitchen of my uncle James Bartley's farm-house". (From Connexional Biography written by H.G. Button, Primitive Methodist Magazine 1876, page 297-299.)
Furthermore John Moore said, "My aunt Bartley was praying when I believed; but there were my brother, uncle Bartley, Walter, and Stephen on their knees at the same time. My brother and seven more had found the Lord at the meeting at Enmore Green the same night, where we had all been."
To my knowledge, John had one sister and one brother. Consequently, I concluded that my great-great-grandfather William Moore found the Lord at a Methodist meeting in the hamlet of Enmore Green, Motcombe, during the evening of Sunday 5th November 1826 at about 20 years of age.
I was truly delighted and amazed to have found such personal and specific details about a relative from nearly 200 years ago. However, once I had absorbed the article's biographical details about John Moore, and stared a picture of him in later life (see below), I immediately started wondering about the identity of Uncle James Bartley, Aunt Bartley, Walter and Stephen. This hobby is a never-ending chain of mysteries - once new facts have been recorded then new loose ends beguile.
