1. I posted his death record - his 2nd wife didn't know his parents' names.
2. There is a possible 1891 arrival for him in one of the early posts, but that Patrick said he was headed to New York. I might look through the Philadelphia arrivals themselves - they were a separate set of records.
3. Thanks for narrowing down the areas of Cork.
4. One possibility left in the US is if he had siblings also in Philadelphia, but so far I haven't seen anyone else named Cotter at any of his addresses. He isn't in all the city directories for some reason.
5. Comparing the signatures on the marriage records - I'd say it is the same Patrick who married both Nora and Delia.
6. He must not have had an obituary, or someone here would have found it by now.
