Hi Annette,
I am getting very lost I did find one mary edwards that came into new york on the date you stated. see below, her fathers name was edward, mothers name I could not read but did not look like Jennet:'( and of course there was also daughter elizabeth, but.... like julie found on the marriage:'( added them after the immingration record. facts here don't add up either this mary edwards was from Ireland. I put in arrival year and mary's birth this was the only one that came close and the only one on this date. Do you have any more information that could help us narrow this down
