Dear Peter - this is a huge coincidence. My Gt Gt Grandmother was Mary Iland, who married William Purvis. They lived in Shoreditcch. Their daughter Ellen, married James Garvey of County Cork and settled in East London. I have assumed that Iland was a misprint for Hand, as I had tracked down only one other Iland, in St Louis, Missouri until I found your e-mail today.
I was brought up in Essex and now live in Guernsey. I'll be doing more research on the whole family later this summer and will keep you posted if my Ilands converge with yours.
Let me know your e-mail address.
Best regards
Nicholas Hall
