Hi,
I don't have any additional info, only to confirm that a Spencer Wallace was born in Kilalla parish, Co. Mayo, on 22 Feb 1789 to a Jacob Wallace. Spencer was the bandmaster father of William Vincent, composer, born in Waterford in 1812.
Ever since I was told that I might be related in some way to W.V. Wallace (I was also born in Waterford), I have become obsessed with the Wallaces, paricularly W.V's travels to, and in, Australia. I have got a fair bit of information about that period, but some accounts seem to differ (dates, places, people). No indication, yet, however, of where my link to the Wallaces (if it does exist)might be!
I believe John Bushelle & Eliza Wallace had a son, John, also a singer, who, I think, died young.
I would be happy to share anything I have with you off-line.
