Leitrim-Roscommon

Looking for advice on how to find information concerning William Carson, born Leitrim, 1886. Wife's given name was Ann (no maiden name).
This is all the information I have unfortunately and I would welcome any help.

Thank you

Shirley:

If William was still in Co. Leitrim in 1901, the record below may be a possible match. There is a two year age discrepancy. Lattone is the townland and Rossinver is the parish
