My GGG Grandmother was Rebecca Avern. She and her twin brother Isaac were baptised in Rowington on April 18, 1791. Their parents were James & Marian. At this point I have lots of other Averns in Rowington but have not been able to prove if this James & Marian are the same parents who baptised children as James & Mary, or James & Mary Ann, or are the James Avern and Ann Burdon who were married in Rowington in Nov 1776. Are you looking for a specific Avern? Rebecca and Isaac were listed in a census as being "Millers" for an occupation, by then living in Southam, Warwickshire.
