Duncan, thanks for the 23 Charles St. info. I will look further into the Blue/Blaune connection. I do have a mass of information on the Rathjen/ Stratton families. Shall I print out from Family Tree Maker and send it to you? I was at PRO yesterday and was excited to find the index to arrival certificates in Britain in the 1830's. Heinrich arrived in Leith on November 4th 1830 and his brother Martin on March 22nd 1834 I will try to find the actual certificates to get more info - watch this space.
