Seeking information on Charlotte Calder, "believe she was born in Ontario Canada about 1850. Her parent were born in Scotland, John and Elizabeth Calder. She is found in the 1870 Census of St Lawrence Co., NY. She is a domestic in the home of John and Eliza Pooler. In 1880 it appears that she is in the home of George and Calestia Davis in Antwerp, Jefferson Co., NY the time as a servant. Mr. Davis was the school principal. Charlotte or Lottie is not seen in the census after that point. I am having a difficult time locating her. I am in hopes of connecting this person to a Calder Family that settled in Glengarry Co., Ontario Canada in 1843 and is seen in the 1851 and 61 Canadian Census. Any assistance would be greatly appriecated
