Hampton-on-Sea

I have intentionally left the ragged edges on this one.  It has been cut from a sheet of other prints.  The caption reads "Hampton, nr Herne Bay. Now long since fallen into the sea."  This is Hampton-on-Sea, which was abandoned in 1916 and drowned due to coastal erosion in 1921 http://en.wikipedia.org/wiki/Hampton-on-Sea

  The wikipedia entry also tells us that the Hampton Inn survives and that could be the building in the distance, more or less central in the photo http://www.shepherd-neame.co.uk/pubs/pubs.php/hamptoninn_hernebay

I believe Herne Bay was a holiday destination for the Mackie family and this picture, which must have been taken no later that 1921, could have been one of Uncle Jack's early attempts.

St. Chad's

The caption on the back reads "A snap of St Chads taken by Bro Hugh (Kenney?)"
The handwriting appears identical to that on the back of the Manilla photos.

UPDATE

I am indebted to Stephen Davies (see comments) for confirming that this is St. Chad, South Norwood

The photo on the parish website shows the 'flat' end of the church. But I have now had a look on Google Streetview and can see how this interior view fits into the outer shell of the building.

Ruins in the Walled City, Manilla

From the Crown Lane archive.  I cannot identify the handwriting, but more of that later.  And I do not know of any relatives who had any connection with Manilla. Top to bottom and left to right the comments read:

"Damaged Catholic church walled city - Manila" (sic)

"Ruins in walled city, Manila"

"Ruined church - Manila. Many of these buildings were unnecessarily destroyed by the Japs"

Presumably this damage was caused during the Manilla massacre of 1945 http://en.wikipedia.org/wiki/Manila_Massacre

The catholic church is San Augustin http://www.etravelpilipinas.com/tourism_news/manila-philippines-san-agustin-church-in-intramuros.htm
