Thanks RTL, but no I really think I can discount this registration/burial. Jeremiah is definitely Jeremiah. The only name variation I have found for him is a directory entry in 1912, Wilmington, Delaware where he is listed as Jerry.
Ellen's birth was registered in Q1 1906. I believe she was named for a maternal Aunt, Nellie Poulton.
In April 1906, Jeremiah arrived in New York on the SS Furnesia. His arrival form says his last address was Newcastle (sadly no specific address).
His wife and child (if the child was still alive) did not accompany him, which was not unusual, lots of men went first to establish themselves, see if it was going to work out and families joined them later.
I have yet to find a return crossing for him, but have another arrival in the US for him in July 1910, this time on the SS Haverford, Liverpool to Philadelphia. That says his nearest relative in the UK was Mrs Nicolson 126 Ayton St, Byker, Newcastle. It also says he had previously been in the US from 1906-190* last character not clear but I think it says 1907. That date fits in with the birth of their second child, John, which was registered in Q2 1908. Jane must have become pregnant with John almost as soon as Jeremiah returned (though he may at least have unpacked his case first <g>)
Jane and so John were recorded on the 1911 census at Clydesdale Road, Byker and in Oct 1911 they joined Jeremiah in the US.
and, after all that, Jeremiah died in Wilmington Delaware in Nov 1912.
Given the dates of Jeremiah's first stint in the US, I think its possible that baby Ellen's death was the reason for his return.
If only they'd not lived in the Newcastle Registration District I could enquire with the local registrar, who are usually wiling to do a short search given the details. Unfortunately Newcastle are not.
But don't spend any more of your valuable time looking for this, you've helped above and beyond my expectations. If I get something concrete, I'll ask for it to be checked if necessary.
Thanks again
