There used to be Geoff and Beryl and they begat Andrew and Alison.
Andrew married Layla a Peruvian who has a daughter called Maria Fernanda who is now 14 and is going through a very difficult stage of not being interested in school and you can guess what she is interested in. They have Mia who is going to be 4 in July and will start full time school in September.
Alison married Derek and they have Alec 9 and Hannah 6.
There also used to be me (Kate) and Eric and we adopted Sammy when she was 6 weeks old. She has married Phil a farmer and they have Thomas 7 and Holly 5.
Now there is me (Kate) and Geoff and we begat Charlotte who is 30. I do have somewhere a shot of our extended families - one with all Geoff's family and one with mine but I fear that would be even more confusing.
