Dave Page lived here in San Diego from the mid-1970s until his death in 1987, and I got to know him and his wife well. By the time I met him, he was no longer playing the pipes, but still played piano accordion and whistle, and he was very generous and encouraging to us younger musicians with an interest in Irish music. John Tuohy, who owns Dave's Alf Kennedy set, is a close friend who I have played with for decades, and John has carried on Dave's musical legacy and repertoire. John and I gave all of that material to Pat Darcy that you've pointed out, now hosted on the uilleannobsession site. Michael Hubbert restored the Kennedy set a few years ago for John. It lives in a case I made for it back in the '80s.
Dave restarted the Siamsa Gael Celidhe Band, with which he had performed and recorded in the '20s and '30s, and inducted his young San Diego friends, who carried on with that moniker for many years after his passing. They included John Tuohy, Judy Lipnick, Ian Law (who are all still close friends of mine) and a few others.
Most of Dave's family followed him and his wife here after they retired and relocated from Chicago, and his daughter and one of his sons are still here.
Dick Grant, formerly of Bray Co. Clare, now lives in the Canary Islands. I believe he may have passed the Rowsome set originally belonging to Dave Page along to Dick's son Liam.
