Hello Brian Many thanks for offering to keep an eye open for COLLING names in your parish, as you do your own research. Unfortunately the only information I have about ANN COLLING is that she gave birth to an illegitimate son, THOMAS in 1815, so I am presuming she must have been born before 1800. The only parish registers to cover this period for Harraton area seem to be those of Chester-le Street, which I searched some years ago to no avail, though I did find many COLLINGS in Chester-le-Street and Fatfield. No, I have no census information about ANN but I believe she may have married after THOMAS'S birth ( An ANN COLLING married THOMAS BARRASS in 1816 in the same Houghton -le- Spring parish in which THOMAS was born.) I do have THOMAS COLLING'S details in all but one of the census records from 1841 but ANN does not feature in any of them. (Thomas married in 1840) Look forward to hearing from you, if any COLLINGS pop up! Regards, Margaret.
