People are so much easier to find in the census with a bit more family knowledge.
I'd not been able to find Christopher TURNBULL in 1871 at all back in 2005. Armed with the newfound knowledge, thanks to contact (via GenesReunited) with a descendant of the James TURNBULL and Margaret JACKSON mentioned on the 19th , I found his sister Mary at last, under her married name (which I hadn't known) and living in Muggleswick. I had searched for likely Mary's of the right age and birthplace, but Mary had rather unhelpfully decided not to record anything at all about her birthplace for the 1871 census and inaccurate data thereafter. Lodging with them was one Chrisr TURNBULL, aged 15, also with no birth place information recorded. And ancestry had made the search even harder by indexing him as Chris FERNBALL.
This newfound cousin has a wonderful photo on GR of Mary with her two brothers Robert and Christopher that comes from a newspaper article on Mary's 90th birthday, saying their combined ages totalled 257.
The TURNBULL chart has been updated yet again.
There have been enough additions/updates to the database that a WorldConnect update to (database LornaHenderson is in train, should be in their indexes in a couple of days.
Had to laugh about the aptness of my comment yesterday about all it taking time. Received a phone call this afternoon from a HENDERSON line cousin who lives in the next town to me. She was answering my 2003 email, but as she was promising photos and a visit including her mother, I'll forgive her the tardiness.
