Thanks for your follow up. I am listing the replies where I can, below:
St Marks Church you will find under www.irish-architecture.com, then buildings of ireland, then dublin, then soth city centre, then pearse street.It looks today exactly as you see.
Emily was born 03/01/1840, baptised 21/01/1840.This I got from the church records locally.
The Humphrey of Baltimore you mentioned, was he of Irish origin, if so, please send anything you have.
Humphrey/Margaret McDaniel 1790, I have listed, but no further information. Humphrey/Anne Odlum, is in my own family tree,fully researched, and as you suggest,his parents areWilliam Odlum Hipwell/Sarah Kingsmill. They were married only 2 miles from where I live.Like wise I have them fully researched.
If you would like to send me brief details on your John/Caroline family, children, and further down the line it would be appreciated.
