Hi Herrmann,
I'm back for more help :)
New branch of the family now. There are two photos with faint writing on the back. I believe it is German, but it seems to be in cursive and it might be Italian or Hungarian. To be honest I have no idea! The first picture is of two Kalchbrenner ladies who came from Felsolovo, Vas, Hungary.
The little boy is Louis Arnold (Born Arnoldini, changed his name). So hopefully it is German and you can read them. If not, I understand, as the writing is blurred and faint.
Thank you as ever,
Debbi Stencil
