Seamus:
The subscription site Roots Ireland does not have the marriage record but there are twelve baptismal records for children of Daniel and Johanna. All were baptized in Kidorrery RC church. The first was Thomas Lee baptized January 19 1840 so Daniel and Johanna likely married in 1838-1839. The last child (Abigail) was born in 1864.
There were four-five Lee families in Labbamolaga in the 1901 census.
