Corrigan-Lagan marriage 1869

Wanted to offer that I have a CORRIGAN-LAGAN marriage ... wondering if it might relate to member John E. Corrigan's own family?

Civil Registration, Ireland Marriages, LDS film No. 101547, records the marriage of 

JOHN LAGAN, of full age, bachelor, farmer, or Knockaleery; father, **CHRISTOPHER LAGAN, deceased, farmer, 28 Aug 1869 to: 

ANN CORRIGAN, of full age, spinster, farmer, of Knockaleery; father, PATRICK CORRIGAN, deceased farmer.  Married by BERNARD MURPHY in the presence of JAMES McCARDLE and CATHERINE KEILTY.  RC Chapel of Killeenan, Pomeroy, Cookstown (Union), Tyrone.

This marriage also appears among the transcribed marriage entries of the Kildress parish records (St. Joseph's):

CORRIGAN Ann (address) Knockaleery m. James (sic) LAGAN, (date) 24 08 1869, witnesses James McArdle and Catharine Reilly.  

A daughter, Rose LAGAN, b. 17 Jul 1870.  (Source: Civil Registration Births, Ireland LDS film #101210.)

**John / James' father, Christopher LAGAN, is my ancestor.
