Aloha! My great- grandfather was Pedro Lujan. He came from Guam to Hawaii and resided in Honolulu between 1870-1910. I know there are Lujans from Hakalau, Hawaii who are descendants of Lucas Lujan. There are also Lujans from Kauai who descended from Joseph Lujan. I am trying to determine if these Lujans are related to my great-grandfather. I believe Pedro Lujan's family was originally from Castilla, Spain. If there's anyone who can help me with my research, I would greatly appreciate it. Mahalo!
