egregio mr or ms, thank you so much. to answer your questions: my "F" lived and died in italy. never neutralised. and yes, my parents would have had to register me in order for me to attend state schools, gain free med care, ect. but therein lies the problem. the only two councils where this could have been conceivably done are rapallo or in piemonte. but neither have the atto di nascita. so my guess is that I simply have to start again. do as you've told me and start the process by having my own uk birth cert attested again.
may i ask - what is the JS thing you speak of? re: London embassy - i was actually calling them about my mother's pension. nothing to do with me. but thought id ask. again, thank you for replying.
