Two surnames? That is an interesting idea. I don't know if Lewis carried it on, but by the time of standardised birth/marriage/death certification, it was just plain old Lipman. No-one in my family is really well-informed on Jewish customs, what with the last Jewish-born Lipman being born in 1845, and my grandad being born in 1939. I'll have to have a look around. Come to think of it, I do have ancestors with two surnames! Michael's mother, if I remember correctly, was called Frances Moses Gomport or something along those lines.
