Hello again
1851 Census:
Maria Maderal 19
Robert Maderal 17
Thomas Maderal 21
Margaret Madrel 62
William Madrel 64 Wool Loom Weaver
Living At Balla Mooar

Interestingly living at Ballaragh were the following family:
Catherine Wade 48 b Braddan
Elizabeth Wade 4
Ellen Wade 7
Jane Wade 10
John Wade 49 born Michael Lead Miner

I am wondering if these were John's parents

There is a John Wade b Braddan that is down as a house servant age 22.

hope this helps

Regards
Diane
