I have been researching the Segina/shegina/stegina name for a few months. Our family name was originally segina but a t was added in the 1930's so I thought. After checking the US census, I found what I believe relatives with the T in the name much earlier. My GF was Ivan(john) segina . He came to the us in1906 and was listed on ellis isl. site as ivan Legina. This has been corrected on the EI site. His Baptismal cert list the Parish of St Mary in Kormanje in the county of Karlovac.Croatia.His mother was Anna Kolar, father was Janko Segina. II don't know if there is a connection with your family, but email and we cancompare .
