Anes and Robert Rennie

Can anyone suggest how I could get further info re the above. Mr Mrs Rennie were listed on both 1881 and 1891 census and on the latter were still living in Peel but then aged 76 and 80. Robert's occupation was a mariner (on 1881).
They were both born in Ireland. I need to know when they arrived on the Island and names of children (if any), also details of their death etc.
Many thanks..Pat
