Floodgate or Flood Gate (a place)

Surely it means that she was 'of Liverpool' when she married, not original birthplace?

You mentioned They were mobile. I'm wondering whether They travelled on the Canal's. There's a Floodgate Street in Birmingham, right next to the Canal

Yes, of course, and John was of Burstill at the time of the marriage.

Burstill is Birstall, the parish that includes Heckmondwike & Batley.
The family were living in Liverpool or she was working there at the time of her marriage.
Church Lawton is in the SE part of Cheshire that immediately abuts Staffs & North Shropshire, so would be in keeping with a nearby Shropshire location. The nearby canal is a possible association with a flood gate. There could have been a flood gate at Church Lawton.
It was just a punt. I don't think we'll make anything more of this unless something appears on a map.

Yes, the Birth Place could actually be a Local Place Name at Church Lawton, maybe the above Link Refers.

[The Geneal Geologist]

Thanks for that. A tantalizing solution.

The Geneologist Website has the 1839 Tithe Maps for Church Lawton, and shows a Farm House, named Floodgate. It is sited to the East of Lawton Hall, and the Red Bull Inn. Could be the Birth Home of Sarah Norbury.
