Hi Alan

The link I gave earlier is for the Francis' entry on the CWGC site. There is no death cert to be got unfortunately from war deaths overseas for this period.
The attestment papers would be the best source to try and establish Francis' place and date of birth, perhaps also next of kin but again, those are proving to difficult to find.
Hopefully, somewhere his service papers may be found or another database where this info may have been recorded?
