My Joseph is on the SynagogueScribes site as Reuben Joseph Lyon GSM 186/17. So far I haven't found his father Saul's death yet either. I have been away for a month but now intend trying to find it! As far as I am aware Saul was a tailor in London but before that I don't know where the family came from, I'm assuming somewhere around Poland/Ukraine but it's early days yet. I have done a Y-DNA test and the close matches I have from that are also in that area so on the right track anyway. Currently trying to find other cousins as well, I can't be the only one doing this
Apologies if this is rambly, been a long day!
