Thank you Lyn for your replies . Re: NY County, beleive this or not but a friend who lives in New York State was helping me with this research and informed me, there was no New York County! However i am on the right track now and and see it does exsist. Think my friend needs to brush up on his geography regarding his own state where he lives lol.

And thank you so much for the death certificate info.. everyone has been a great help. I am new to all this research of familys.. so i appreciate any help, info there is . And living in the UK, doesn't help the speed of things when the research is needed in the US.
Kind regards Janette.
