Hi Teri - I am attaching the Burke's stuff. Guess who sent it to me ages 

ago? David Hillman! There's a nice bit of small world for us both today.

I am also giving you access to my family tree. I will be honest, it's an 

embarrassing mess. The people closest to present day are in good shape and 

reliable with good sources, etc. but the folks back in time are awful. I'm 

trying to clean it up but it isn't there yet. So take it with a large grain 

of salt. Also, it's got both my line and my husband's. You want to be 

looking from Sarah Mary Vosper (1928-2012), my husband's mom, on back. Her 

Vosper married into the Arnold family, who were loyalists in Canada. Her 

John Vosper ancestor had a criminal record in the UK for larceny, which is 

why I think he ended up on this side of the pond!

Nice to meet you - I'd love to be included in anything you've got going on 

research wise! Let me know anyway I can help.

Best, Cate Williams

(I'm also sending the original email I got from David Hillman circa 2006-ish.)
