This is the information that Erika Giftge graciously send me in January this year.
It came from the records of the Baddeckenstedt church and represented the only Burgdorf in the area in that time frame. I point out that his name was spelled Burgtorf.
Philip Burgtorf married Dorothea Ahrens on 19 Nov 1819, he was 30 and she was 20
at the time.
Johann Carl Heinrich born 18 July 1820
Johann Heinrich Philip born 26 March 1822
Johann Heinrich Wilhelm born 17 March 1824
Johan Heinrich Conrad 1 April 1826
Johann Heinrich Friedrich 14 Jan 1831
Wilhelm Christian 18 Jan 1831 ( Christian and Friedrich both born same year, 4 days
apart. Maybe twins or typo?
Theodor Emil Clemens David born 23 March 1841
I suspect that Johann was a name given to males as was Mary given to females and was not the name they went by.
Erika did not tell me if this was a Catholic or Protestant church although I think in other correspondence she said it was Protestant. At the same time she searched the Gross Elbe records and I have searched other nearby towns. This is as close as we can get. If only he had used his full name on the Hamburg Emigration list. I am firmly convinced that J.W. and Julius Wilhelm are the same. All parts of the puzzle fit perfectly with my findings in New Orleans.
