Husbands in Sneem

I've been having trouble finding information about an ancestor's parents.  The parents of my Anna Husband(s) are listed as Charles Husbands & Mary Coffey on her US death record.  I have not been able to find any other information about that couple.

Annie was born in Ireland about 1853.  She resided in Sneem, & married Michael Sullivan there in 1872.  He was from Kenmare, & they lived there until they left for the US in 1883.

I don't have a birth/baptism record for Anna, & her civil marriage record just gives her father's name (no parents on the church record).  I know there was a Charles Husbands that married a Margaret Neil in Kenmare in 1853.  Did her mother die & her father remarry?  Is her mother's name incorrect on the death record?  Unfortunately, I don't know.

I also want to note, from what records I do have, Annie seems to be the same age as her husband.  Her husband was born/baptized in Kenmare in 1853.  They were both said to be "full age" on their marriage record, & I was told "full age" was 21, but Michael was definitely only 18 when he married.
