Well found Isobel, at least that proves that the David Schulman born in Scotland c1882 was indeed an auctioneeer and is almost certainly the right chap.
Sounds like he got a girl pregnant,so he was indeed Eveline's dad,but maybe didn't marry her mum.
Hence her not being quite sure what her maiden name was,and the Scottish link of her moving back there,and dying there,is explained too.
