I am not sure where the name Dansey came from on this profile, or the location of London, England but Mary Parsons born in 1792 - died in 1874, married William Parsons. And they had among their children a son named Edwin. Are you assuming she is a different Mary Pearson? The name Dansey should be removed and London, England as she was born in Maine, and son Edwin should be restored to the profile.
