One in particular caught my eye.
I thought, "Hang on ... wasn't Clara one of John Neale Bethell's wives?" This being the John Bethell buried at St Ninians in Avondale. The answer is yes.
The above headstone, for John Bethell and both of his wives (one, Catherine, died in 1900; he later married Clara, who died in 1918), leaves off the second "e" in his middle name Neale. Was it installed later, after his own death in 1943?
I had wondered why the Bethell headstone was part of the same block as that of Jessie Ingram, the wife of an Avondale postmaster (1902-1906) Duncan Ingram.
A Miss Jessie Bethell was noted in 1895 as having found a message in a bottle in 1895 on the West Coast of the Waitakeres (perhaps close to Bethell's Beach? -- Brisbane Courier, 8 October 1895, p. 3), so at some stage she may have married Duncan Ingram -- and was buried in the Bethell family plot here in Avondale. A number of the Ingrams married Bethells, according to the Presbyterian Church marriage register.
But -- that still doesn't explain why and how Clara's headstone ended up all the way over in Western Springs, close to Chinaman's Hill. As soon as I find out more information, I'll post an update.
