This is not a discussion topic. As there isn't a tab titled "Errors", this seems to be the only way to bring mistakes to the manager's attention.
This posting says that Justice James De Havilland, of the Royal Court, is a half brother to Justice James De Havilland of the Royal Court. I rather doubt a man can be a half-brother to himself. Furthermore, the other two men - Thomas and Andrew - listed as his half-brothers are his full brothers as both of them have the same mother and father as James.
Both of these errors are easily remedied by simply deleting the last paragraph listing half-brothers. By deleting that entire paragraph, the duplicate record for James de Havilland will automatically disappear.
