OK - nit picky time.

There are no marriage certificates for 1815.
Do you have date and parish?
I can't find it on the IGI.
Their first child seems to have been baptized in 1816, so 1815 is quite probably correct.

1841 census.
Place of birth was not recorded.
The family were living at Glenrushen, Patrick.
Ages are probably rounded down.

The 1854 burial was at Malew not Patrick.
