James, I noticed your kind reply to the NIR-ANTRIM post regarding information about the location of Tyrone St in Belfast. Perhaps you could also help me locate the whereabouts of some ancestors who lived, according to a letter they wrote in 1867, at Abbotsford Place, 243 York St, Belfast. According to their gravetone, when they died in 1891, they had lived at Cherrymount, Belfast. I've looked at a contemporary map of Belfast but couldn't quite figure out where these addresses were. Thanks for any help. ~ Colleen in St Paul, Minnesota, USA
