What is Ivy's baby brother/sister called?

[coldtoe]

Just that really. If you know an Ivy, what is her brother or sister called?

My grandmother had sibling Arthur...

My dd could have a sibling Jack.

Atticus, Rory and Clarence would also be contenders.

I know two little girls called Ivy and Rita!

I think Nancy, Pearl, Gina, Polly, Lydia and Nelly are good with Ivy.

Ernie, Victor, Seth, Jack, Freddie.

I know an Ivy with a brother named Jake.

I know an Ivy who's siblings are Nellie, Alice and Thomas.
