My question is where is Ann Edwards husband as he does not appear with her in 1881 1891 or 1901 and husband Charles looks as if he was institutions. There is a 6 year gap Thomas and Selina. If Selina is someone elses child then she may be registered with a different surname. I have been searching on the Cornwall OPC site bit cannot identify selina
