I hope somebody will be able to advice me the content of naturalization records. A guy arrived to UK along in about 1880+. He is listed in 1891 census at ancestry.com. He lived in native contry(Russia) a wife and a son. I were not able totrace him down in arrival lists. Perhaps, in naturalization records for him in UK (in any) will be data about his family content left at the motherland, or its useless to try check them for this?
