John, nephew? of Anne

I have started this blog to share old family photos with other family members and to enlist their help in identifying some of the people in them.

The First photo is one from my grandmother's collection (Annie Louisa Barrs).
It has the caption written on it: "To Aunty Ann from John 1 year".

In my records I don't have a record of a John as a nephew of my Nanna. I assume he is from the Barrs side of the family.

Any help would be appreciated.
