Is this your Thomas Ryan? This was the only reference I could find for a Thomas Ryan. It is the right time frame but not sure as the executrix is not the wife you named. The only suggestion I would have for you would be to check deed indexes , grantors and grantees and to check any wills and estate records for any early Ryans in Burlington County. Even if you could find an obituary it is unlikely it would name Thomas' parents. I am assuming that the death record from Trenton did not name Thomas' parents? I think that you could order some of these indexes from your local FHC or you could hire a researcher in Trenton if you can't go yourself.
