Google Streetview shows The Family Church at 81 Jumpers Road. However, it doesn't seem to have a web presence, and there are no obvious signs to see in the 2020 Streetview.

St. Luke (2021 Streetview) on Salisbury Road. It also pre-dates a map of 1898. SZ 1667 9487. Link dates it to 1874-6. Grade II listed. What is likely its predecessor shows on a map of 1872, nearby, at SZ 1659 9490, as Church (Chapel of Ease). The best Streetview of it is from 2008, though it was still there in 2021, in use as a nursery.

Mudeford
All Saints (2019 Streetview) on Mudeford. Building works were underway when seen by Streetview in 2023. The church website advises of a fire in 2022, since when services have been held in St. John's at Purewell, and in Stanpit village hall, on Stanpit - seen here by Streetview in 2023.

St. John on Purewell, as seen by Streetview in 2023. It's dated here to 1880. Curiously, it isn't labelled as a place of worship on any available O.S. map, although some apply the label Hall to it. SZ 1702 9294.
