Why would someone born in London of British parents have to be naturalised?

You could always ask them for a quote, it must be cheaper than travelling down there, or maybe not 

Definitely cheaper, but I have a l-o-n-g list of things I want to look up at Kew!

Sounds like you need a short stay down there,  Kew Gardens are as far as I get I am afraid.

Able Seaman Henry Gilbert Prignits died 1 June 1945 buried Lambeth Cemetery (find a grave)
ADDED
Did some more digging per GRO index he was 24 years old.So Grandson of Henry and Milly by their son Henry Otto Gilbert Prignitz.

Thanks!

CWGC says he was the son of Doris M Prignits but his birth was registered as both Gymer and Prignitz (and indexed as Priguits so no wonder I didn't find it before!), mother Gymer. (Parents' marriage indexed as Prignite and Oymer!)

I have done that a couple of times before, but my free accommodation there is no longer available as my host and hostess are moving away from London

Thanks to everyone for help. I have now checked all the references to Prignit* and Prigu* on FreeBMD and FindMyPast, and have quite a lot of information about the descendants.

The only one I can't fit in is Elisabeth A Prignitz, who married Frederick G Goudie in 1952.
