Welcome to rootschat. You will find plenty here.
John was a Royal Marine stationed in Egypt He married Rachel Golubjoz aboard his ship H.M. Monarch in Port Said. They came back to Spennymoor Co Durham. Rachel and John had four children none of them survived. John married Mary Ann Harrison in 1887. I cannot find a death certificate for Rachel.
James Keyland married Sarah Wilson in 1856, Antrim, Irleand. I am certain the father of James is a William Keyland born about 1811, he married a Elizabeth? As per census below
8 BALLYMACREVAN TOWNLAND , Ballinderry County Antrim (1851 Census)
WILLIAM KEYLAND, HEAD, M, 40, FARMER, County Antrim,
ELIZABETH KEYLAND, WIFE, M, 36, NONE, County Antrim,
DANIEL KEYLAND, BROTHER, U, 50, FARMER, County Antrim,
ANN KEYLAND, DAUGHTER, U, 8, NONE, County Antrim,
ELIZABETH KEYLAND, DAUGHTER, U, 6, NONE, County Antrim,

Yes you are right the family disappear during the 1881 census. Maybe a trip back to Ireland over that period? It seems as if most of the men of the family were coal miners. Durham was known for it's mining.
I still can not find out why on earth Sarah Keyland traveled all the way to New Zealand at the age of 15.
