We get a lot of requests involving Sicilian genealogical research. The subjects of Sicilian genealogy and family history are covered on several pages of Best of Sicily. Specific pages are also dedicated to related topics such as surname histories and heraldry (coats of arms).
However, we do not engage in genealogical research, though we can sometimes recommend a competent genealogist - depending on where in Sicily you require research and what kind of records you need researched. Incidentally, those we occasionally recommend are not necessarily the ones you find with web searches, while some websites on the subject present flawed information. Ours at least has the virtue of being accurate; it won't mislead you.
