Hi Valda,
The name of the wife in the will of John White of White Cross Street is Judith. I don't know the name of the wife of my John White. All we know is that he was "a celebrated hunting squire of Harrow Weald" and that he is supposed to be buried in the church in Harrow but we don't know when he died. Thomas was born c1732, possibly in Harrow Weald, he is a younger son and he is buried n Saint Luke Old Street, Finsbury. So we are looking for a John White born c1700 perhaps who was presumably married in the 1720s. We need to find out if there are any burial records for Harrow Weald around that time and see if there is a White family recorded.
Best wishes
Philippa
