Last thought for the day and no hurry on this one.
There is this:
Joseph Oppenheimer, merchant, has a business at 52 Brown Street & a
house at Crowcroft Cottage, Levenshulme in the early 1860's and later was
listed at York House in Oxford Street where Ludwig had also been.
I'm wondering if we can establish a connection between them on the 1841 or 1851 census.
Many thanks again for your time and energy.
