Hi Elizabeth,
I briefly looked through your previous thread. Perhaps the following was mentioned, but I didn’t notice the items.
Have you tried contacting the Holy Names Cemetery office to see if there are any helpful details recorded in James’ burial records? If not, possibly his exact birthplace was recorded and with luck there may be additional details. I contacted the office several times when researching my husband’s relatives; the staff was always very polite and tried their best to help.
1849 was mentioned for his immigration date. I have yet to find most of my ancestors sailing to North America. You stated
“But I think my GGF came to America in 1849 with his Mom and Dad, Thomas Hamon and Caroline Cooper. At least, this makes the most sense at the moment as I can't find any other records of a James Hamon immigrating in those years.”
Perhaps I’ve just been unlucky with my ancestors but I think it’s more likely that his sailing would not be found rather than actually finding him on a passenger list. Perhaps you checked Canadian passenger lists as well?

I just briefly searched, but I didn’t see any other results for Jacob Hamon, so possibly he was not related to James.
Added: again, perhaps this was previously mentioned but could this be Delia’s father:

Perhaps Michael was his son, who worked in the saloon?
