Hi
My husband is Romanian ( im Irish) i asked him did he know anything about getting a passport through ancestors. Unfortunately he is not aware of the rules but he says probbaly like everything else in Romania it will be along slow process
Here is a link to the romanian embassy in London
www.roemb.co.uk/ You can email the consular section or telephone just be warned that they dont reply very quickly to emails
There is hardly any information regarding Romania and passports on the net and if there is the information is usally out of date or current so i would imagine actually getting in touch with the embassy is your best option. I really do not know how beneficial a romanian passport is . It does look like Romania will join the EU but alot of the western europe and America look down on romanian passports thanks to some over publicised romanian gypsies. We know from experience how slow the process is in ROmania for getting paperwork and formalities resolved but maybe know with the new goverment things may start to change and you will suceed in getting your passports. Sorry i couldnt be more helpful
