Once again, Mike, thanks for your helpful reply. I did write a reply last night, but when I came to Send it RC cut me off, saying the site was too busy, and I lost the lot!
I certainly learn a lot on this site - I wonder why Jews were banned from Leicester by King Charles? As I said, I'm clutching at straws now - have looked so long for the grave of my great-grandparents (in the hope it might give just a crumb of information about them). You have already been extremely helpful in the past, but it seems that they were determined to die without leaving any paper trail. A throw-away remark by a relative has made me wonder whether Julius was Jewish - apparently the surname could be either Christian German or Jewish. The couple were married in 1885 in Leicester register office which is not conclusive proof either way. Julius's father is unnamed. There is no record of him at Kew either, and nothing in The Times archives or the London gazette.
The CDs I have bought in my search have been:
Welford Rd 1849 -1890
Welford Rd 1849 - 1950
Leics & Rutland Vol2 1813 -1891
National Burial Index CDs
I also found a website with graves in Barrow on Soar, which is where they died
No success in any of above. I'm very interested in the CD you mention. As I have several mystery Leics ancestors it might be worth buying it. Julius and Maria died in 1889 (he first appeared in 1885 at his wedding - so he managed to avoid any censuses!). Would the new CD have any extra burials from the late 1880s?
Thanks again for the trouble you have taken, and the help given Mike.
I don't know why I don't just give up on this one, but it's the one mystery I'd love to solve.
Lesley
