Hi,
I have a great, great, great grandmother named Ann Ivison who had a sister named Sarah (also Margaret & Ellen). Ann was born in Manchester, England on January 30, 1797. She travelled to Philadelphia, PA in 1826, married an Englishman named James Simpson and settled in Illinois. They started a large farm and their family were on that land for 4 generations. The last generation (my father & siblings) sold the farm in the 1970's or 80's. I have more data if you're interested.
