Wondering if there may be a link between yours and mine.
Have you any info prior to your John Christian Frederick GAEDE? I have a Friederich Christian Diederich GAEDE b 6 August 1803 in Schleswig-Holstein, Kiel - d 25 Sept 1862 in London. He m Marie Marguerita Sarah HORN.
Friederich's parents were Gottfried Joachim GAEDE and Christina Magdalena WENDTEN. Any bells? I have more info if you are interested. My e-mail (as I hardly ever get to these boards) is email@example.com
Kind Regards, Julie
