Chris, if you google isle of man genealogy & then Lawson's index of burials you can find deaths. You can also click on marriages.
There is one Jemima Keig age 41 Malew death /burial 12 April 1891. There are about 4 Joseph Keigs burials in Rushen, Lezayre & Ballaugh. Hope you manage to get the site. KayN
