I recently discovered a connection to the Holmes family through a fourth gt uncle John Hanson of Coleraine who seems to have married "Ann Holmes" their Son James Holmes Hanson (married Ellen Drummond) and eventually moved to New Zealand where he has descendants . I
have a few references to Ballymenoch House through the Hanson family .
There are connections to the Tomb family and Mc Grottys of Coleraine.
The second son of John Hanson and Ann Holmes "John" was agent to Thomas Greg Merchant of Belfast his daughter married Arthur Coates, He had one son Thomas Greg Hanson who died in India
Any further information or any exchange would be interesting
