Doug needed a girl born Sept 15 1901 to match the birth date of the affidavite Maria Van Siclen. He found one.
That represents the End.
The means - transpose the girls mother to be the wife of Cornelius Van Siclen in the Brighton Cemetery. Do not verify that the maiden name of the girls mother is identical to the maiden name of Annetje Lawson until after the transposition is made then rationalize the transposition by referring to the birth record of Annetje Lawson who's fathers name is known.
Ergo - The end justified the means to reach the end.
