Could it be possible that Ida Berry and Annie found in the 1900 census be the same person ?
James Reeves married on Nov. 8, 1880 to Ida Berry in Philadelphia, Penn. and then on the 1900 census we found him with Annie and the marriage date given in this census is 1880 and she is said to be the mother of 4 children living.
When James married Margaret Haynes on April 7, 1910 in Delaware it is his 3rd marriage so if it is really the same James who married Elizabeth Whitelam ????
The mystery in this research is sure the fact that we are not able to find David and wife Mary Booth on our Canadian census. I tried to find them from 1850 up without success.
Hope this is not more confusing for you.
