Tarpey/Kenny

Thank you, Sinead, for directing me to the proper place for this!

In 1848, my ancestor, Ann Tarpey, placed a message in the Boston Pilot looking for her husband, James Kenny.  She listed her home as follows:

County: Mayo (I know that has changed)

Parish: Kilcolman

Townland: Ballaghardus

Barony:  Clanmorris

Poor-Law: Claremorris

Ann and James had two daughters, Mary T. born in Ireland around 1843 and Bridget (Delia) Irene, also born in Ireland, around 1848.

I believe Ann Tarpey was born around 1820 and her parents were Marion Finley and David Tarpey.  

I am interesting in finding out:

1. What are the birthdates, marriage dates, etc, of the names I already have?

2.  Who were James Kenny's parents/extended family?

3.  James Kenny was some sort of linen or cloth salesman/merchant.  He was on a sales trip to the US when he disappeared and was never heard from again -"sailed from Sligo, 2 March 1847, in the brig Imperial, Capt. George Salter, and landed in New York, April 19th, 1847".  I assume this not a passenger ship, as I can find no record of it in lists.  Were textiles a common industry in the Kilcolman area?  Would there be any record of his business or that ship somewhere?

4.  Who were Marion Finley and David Tarpey's children?  I know that several came over to the US.  Did any remain in Ireland?

Thank you for any help you can provide!
