I think the points need to be transferable to a new name (either change of last name or to a farm name) when a marriage causes a name change!
The marriage only caused the last name to be changed and as I said that is no problem. Marriage doesn't cause a farm name change. Since Jan's farm name is new (not an existing name with ABC points) we can probably transfer her points under Jan Burke to it. It would probably be best for Jan to email Jean with the request to transfer and have the Board discuss it and vote.
We wouldn't ever what to go the other way though. Say a family has accumulated points under their family name (with a family membership) or farm name and there is a divorce. Not knowing which family member was the main force behind the points earned I can't see dividing the points among the individual members. One person would either continue under that family/farm name or start over cumulating points under a different name.
Also, say two individual members start showing together under one name like, A & B Poultry, we wouldn't transfer existing points earned by the individuals to A & B Poultry.
I know many members want to have farm names and I've even included a line for that on the membership form. The reality is it is easier for many of us (secretary, points keeper, awards presenter, etc.) to deal with one name and not have to cross reference member names to farm names. This is the main reason all new members on the forum are registered under their real names. A few years ago it was a monumental task figuring out what user name related to what member name.
