Family of Sarah Mylrea b. 1836

I recently asked about Sarah Mylrea b. 1836 in Douglas. I have info from the1851 census. Her father was Philip Mylrea a stonemason, his wife Jane (nee Moore). They had another daughter Elizabeth and a son, John. Would it be possible to find out if they appear in any of the other census years, I am having trouble finding them. Sarah married in 1868 in Toxteth Park, Lancaster but I don't know if the family stayed on the Island.
Any help would be much appreciated, many thanks,
Carolyn
