The Villa Crivelli near Inverigo is apparently in disuse since the 1950s after the last Marchese died. There is a Facebook page Amici del Castello di Inverigo which shows photos. On another website, it says that the Crivelli family moved to Milano after Napoléon abolished aristocracy in 1797. Following the descendants of Flaminio Crivelli on Geneanet mentioned as the founder in the 16th century, the contemporary of Thomas Rivers would have been Tiberio Crivelli, Milanese patrician, Marchese di Agliate (7th, September 10, 1821 - February 8, 1882), Signore di Rancate, di Verano, di Robbiate, di Varedo, di Dorno, di Lomello, di Lambrugo and di Busana Inferiore. All of these places are south of Inverigo, except Lambrugo. This seems to be a distiunct Crivelli line, not related to those mentioned earlier. The last Marchese di Agliate listed on Geneanet is Uberto Crivelli (1905-1973), who is also mentioned on some of the websites mentioned above.

There is also a parentage tree of Giuseppe Gabriel Balsamo Crivelli on Geneanet. He was Marchese di Zelo Surrigone, a small location southwest of Milano. No connection evident to Como. Was Professor of Natural History in Pavia and died there.
