We have recently discovered my mother and aunt were adopted during WWII (sent to countryside to avoid the blitz and never returned to birth family). Any suggestions on how to start trying to identify birth parents? We have almost nothing to go on except their first names and birthdates, which were likely not changed by adoptive family, as they would have been 5 years old when relocated. However, there is one quite unusual piece of information that could be helpful -- they were twins born a few days apart from each other. Thanks in advance for any ideas, suggestions.
