Hi there! I think I might have something for you! I came across Lydia and Thomas in tracing back my Ickeringill direct line. I have them as parents of David, aka Ickringill or Ickeringill, Gill (and numerous other variations in the transcriptions), born Halifax, Yorkshire, 20 Feb. 1803. There are two near-identical listings of David Gill's birth, one in the England and Wales Non-Conformist and Non-Parochial Registers (1567-1970) and the other in the England, Select Births and Christenings, 1538-1975, both listing parents Thos Gill and Lydia Gill. What ties this together is the birth of George Ickeringill, 13 Dec 1805 in Bradford, Yorkshire which gives parents as Thomas and Lydia Ickeringill - meaning that this is presumably my David's younger brother. (There are also some other likely siblings which you will find if you do a parent search on the IGI searching on surname ick* and first names Tho* and Lydia: Thomas Gill (not certain about him as he was born 1797, before the marriage date), John Gill, born 1798, William Gill, born 1801, "my" David Gill, born 1803, George Gill (born 1804) and Joseph Gill (born 1808). I hope this is helpful. Btw, I saw the possible father of Lydia as being a painter and David was a painter too; not sure if this is significant. Good luck with your search. Nikki.
