My Purser line is from England around the Cotswalds area - place names such as Hidcote Boyce,Glou. Ebbington, Stretton on Fosse etc. and in my records, date back to one John Purser born c. 1560 died 1635. Current family members still live around Ebbington.
The Welsh line is also known to me, as is the Irish line. Reese Purser (?? - 1698) seems to be the first known member of the Welsh line and John Purser (??- 1781) born Tewkesbury, England; died Rathcornick, Ireland? seems to be the first known member of the Irish line.
To date, I have not been able to establish any link between the three lines.
