Hello again Heywood
Home now and have access to my tree.
I did have it in my records (advised by a cousin who used to tinker) that Eliza Milner was born in Armley. I assume that is around Leeds. So the Armley/Leeds link sits well. And the other entries you provided (including the transcription error of Elvia) would ring true as well. So that is quite a bit of information on Milners.
As we agreed earlier, the references to Charles Henry, Frederick William and Emily Hall are correct.
I have no record of the marriage date etc you mention is on FreeBDM for Thomas Henry & Eliza. I assume that is trackable online from which I could order a marriage certificate to get parent's names? It would appear that we know Eliza's but suppose the certificate would rubber stamp that. As for Thomas, his mother is Mary (someone) and by 1851 is a widow.
The entry in 1871 showing Charles Henry Hall (my g.g.grandfather) residing with Milners as a 17yo is excellent. Closes the gap on tracing where he was and what he did before heading to New Zealand. To be honest, we don't have a lot of knowledge of him there either except for some addresses, a load of children (10) including my grandfather, and his death. But I am assuming that something either attracted or drove him to NZ. Eventually it would be nice to locate him on passenger list for his travels and from that to see if he travelled alone or with other family members.
