Hi Andy,
Sorry not got back sooner been away. As you rightly say Spencer Pash did produce a comprehensive family tree, but this stopped with the Pash's at 1848 and then followed a maternal line. I have now taken the Pash's back to c1740. They were London based and your's and Anne's Australia line start with Frederick's widow Mary going there in 1849/50. Once you have made 3 postings I will send you a personnal message with our e-mail address. Anne would love to catch up with you and your news.
John
