I am having trouble locating a record of the Dorogokupetz family coming into the US. I have found the mother Elena along with her children Tatjana, Philip, Spiridan, and Wladimir coming to the US on Oct.14, 1913 on th SS Russia. However there is no record of the husband William. The thing that has me confused is that I have also found them on the 1910 census from Iowa. The name is spelled incorrectly (Boregokeyostz), but it lists William as head of household along with Helena (sometimes seen as Elena), and their children listed as Lanie( this should be Tatjana, possibly shortened or mispeeled), Philip, Uladdi ( I think this would be Wladimir on ship manifest), The other child that was on the 1913 ship manifest was not yet born so is not on the census.
So here is the basic problem I face. I have found them on the 1910 census. But I cannot find any ship records until 1913 and that doesn't include the father. Family stories say that the mother went back to Russia at least once and maybe more when she had children. I am not sure if this is in fact true though. According to census records, William came to the US in either 1906 or 1907 and Elena(the mother) along with the three oldest children came in 1908. I need advice on where to look for other ship manifests. I cannot find anything earlier than 1913. Can any tell me where else I could look. I feel like I have tried everything including scrolling through anything starting with a "D" since the name was often mispelled. Thank you in advace for any help.
