This isn't the location of St Eloy's/Loy's Well. It was a bit north of here, just west of The High Rd, near present-day Bruce Grove station. This link also refers to other sources eg Tottenham's famous 1619 map https://www.thenorthernantiquarian.org/2021/01/19/st-loys-well-tottenham/
Something is not right. This message is just to keep things from messing up down the road
