Thomas Neary b.c. 1833 in Roscommon (tombstone) emigrated to Baltimore, Maryland in April 1852 (ships list which confirmed family story). Married Elizabeth McGuigan October, 1852 ( church record which also confirmed family story). Only reference ever for reason for leaving was " things got difficult after a landlord was killed, and his brother was going to get all the land anyway." That sure narrows it down!
Children: John,James, Margaret, Elizabeth, Patrick, Thomas, Ellen, Winifred, Sarah, Joseph, Annie, William
Griffith's shows the great majority is Nearys in the Northern prt of Roscommon. and , of course, almost every head was named James or John. Same with the 1901Census
As for the children's names, Margaret was also the name of Elizabeth's sister who also came to Baltimore, Ellen was supposedly Elizabeth's grandmother and William her grandfather.
Below is a picture of Thomas Neary probably taken c. 1880
As soon as I saw the mention of a Roscommon landlord being killed I immediately thought of the londlord Major Denis Mahon. You can see from this link that he was killed in Strokestown in 1847. http://www.fourcourtspress.ie/product.php?intProductID=815
There are estate records available for Lord Pakenham-Mahon. These are at the National Library of Ireland Ms. 10152 and date from 1725 to 1854 for all records. The parishes mentioned include: Bumlin; Cloonfinlough; Elphin; Kilgefin; Kilglass; Kilnamanagh; Kiltrustan; Lisonuffy; Shankill and Kilmacumsy.
You already have the church record for the marriage. Where did they get married?
You could also try checking the land records called the Tithe Applotment Books (1823-38) or the later Griffith's Valuation (1848-64). Griffith's is freely available here: www.askaboutireland.com or here: www.failteromhat.com Failte Romhat has lots of other useful links you could try looking at.Tithe Applotment Books (1823-38).
