Thank you so much for the welcome Gwyl, JesseLee and Arup.
Arup, it is a coincidence when you mention your Irish heritage and the famine immigrants as one ship replica which I intend to build is the famine ship "Jeanie Johnston" which has a connection to Tralee in Ireland near to where I am living. It is a well known ship in Ireland. Some info can be found at https://en.wikipedia.org/wiki/Jeanie_Johnston. The good news story in relation to the ship is that there were no deaths attributed to the ship in its lifetime of sailing even when it eventually sank. I attended the launch of its replica in 2000 and it sits in Dublin port today as a tourist attraction.
As a matter of interest to yourself and tracing your relatives have a look here. http://www.thejournal.ie/irish-parish-records-online-2-2636877-Mar2016/.
Stay safe.
