My husband's greatgrandfather was Luigi Castaldo who married Carmela.They had four sons, Peter, b. July, 1891; John, b. March, 1894; Anthony b. March, 1896; and Consalvi, b. May, 1900. John (my husband's grandfather) married Catherine Keegan and together they had two sons: John and Martin. I have found Luigi and Carmela in the 1900 and 1910 census, however, I cannot find them after those two.If anyone has information regarding these two people, please contact me.Thanks.
