Coath family

[judy81]

Hi.

I am looking for information on the Coath famiy of Geurnsey.

My Great Great Grandparents were William John Coath and Mary Ann Steward /t. They are listed on the 1841 and  1851 Census at St Peter Port, then they disappear completely (or so it seems).

One son, Robert George,  served in the military and is on the 1861 Census an 'Inmate of hospital workhouse, St Peter Port, widower, aged 30.  I cannot find any records of his marriage or death. 

Ann Maria married Alfred Tomes and Richard and Susan came to Australia.  No evidence on what happended to Mary Selena. Originally the Coaths were from Cornwall.

Is there anyone with any information, please.

Regards
