I searched the Irish Family History Foundation's database. It contains 12,000,000 surviving rcds for abt 65% of Irish counties. Rcds B4 1840 are increasingly sparse, B4 1800 rare. I only search the existing database.
For Samuel Owens B ???? in the Parish of Trim in Meath, I found 1 B rcd. This is for a Samuel Arthur Wellinton Owens B in 1855, Church of Ireland. The father's forename is Edward. This fits your data nicely. A view of the detailed rcd SHOULD show the parents' names.
For Edward Owens M ???? in Co. Meath, I found 0 M rcds. I estimate his marriage date to have been 1835 +/- 4 yrs. 33 of Meath's 40 parishes were keeping rcds by 1835. Edward and Sarah may have married elsewhere.
Google the Foundation's name to lead you to this database. Try entering the data for the other 9 children. Pls post your search results to my genforum msg.
