Hi Stella The time frame for my research is before 1558, as Thomas Hillersdon married in Toddington in 1558 to Joan Potts and I am unable to find his birth or his father. It is probable that he was born in the Bedfordshire or Buckinghamshire areas but am unable to get past this wall. Thank you for your quick reply and the information you have sent as it is very useful to me for my research. Thank you Jan Hilsdon, Toowoomba, Australia
