I've got an idea about RichJohn (genius coinage!). If his GCSEs are really not great, he may leave school and come to work on Bridge Farm. They could do with an extra worker about the place and it would give the SWs a brilliant chance to explain lots of basic farming/country stuff to us.
He could then set his cap at Phoebe who is the same age, I think, and that would really put Josh's nose out of joint.
Trying to work out the relationships here:
Generation 1 - Dan and Doris Archer (married)
Generation 2 - Jack, Phil, Christine (siblings)
Generation 3 - Jennifer, Lilian, Tony (siblings); Shula, Kenton, David, Elizabeth (siblings) - the one group being first cousins to the other [I'm deliberately ignoring Christine's son Peter as he never speaks and I don't think he has any children to add to the mix]
Generation 4
- Adam, Debbie, Kate, Alice (siblings); James; John, Helen, Tom (siblings) - all first cousins;
- Dan; Meriel; Pip, Josh, Ben (siblings); Freddie & Lily (twins) - all first cousins
Generation 5
- Phoebe, Noluthando, Sipho (siblings) - as yet these are the only grandchildren Jennifer and Brian have
- soon there will be Baby Snellamy (offspring of James and Leonie)
- RichJohn and Henry (first cousins)
I get lost when it comes to cousin relationships. The nearest I can get is that Phoebe is a cousin several times removed to both Josh and RichJohn.
