Bob Leuzarder re-contacted us in 2020, and subsequently provided data in the form of refs 324, 325, 327, 328, 329 and 331. He introduced us to Jeannine Wegmueller of the Luzarders (ref 314), and provided a useful link to data on the Midwestern Lousadas (ref 332). Before this he and close relatives, plus Jeannine, participated in John Griffiths' autosomal DNA study. We were encouraged enough to include the Leuzarders and the Luzarders in our main genealogical database, in accordance with a chart showing a hypothesised link between the USA Lousadas and the English Lousadas.
