The passenger list for the SS Noordland, which left Antwerp on 23 December 1899 and arrived at Ellis Island 5 January 1900, includes Max, Buna and Chane Pickholz. (see lines 15, 22, 23) I find it unusual that Max and Buna are not listed on consequetive lines and I don't know if this is significant.
The entry for Max tells us that he is twenty-six years old, married, can read and write, is a US citizen and is headed for "home" in NY. (After "NY" is something unclear which looks like "disau.") Max' passage was paid for by "Brother-in-law."
Buna is twenty-three, married, cannot read or write, is a US citizen and is headed for Brooklyn NY, with the same "disau" as Max. Buna had previously been in the US for eight months and was going to join "husband, Max Pickholz" in Brooklyn.
Chane is seven years old with all the same information as Buna.
Now we indeed have a Marcus Pikholz, born 1873 in Skalat, who is most certainly the Max Pickholtz of the DORA family. We have two problems in accepting this Max as the one in the passenger list. First of all, on the 1913 marriage certificate (Max and Sylvia Brock), Max says he is single and that this is his first marriage. Secondly, Max cannot have a daughter named Chane in 1900, becuase that is his mother's name and she lived until 1923. It is or course possible that Chane is Buna's daughter from someone other than Max and that the child Chane took her step-father's surname. In any case, we have no further reference to either Buna or Chane.
We seem to have no other candidate to be the Max on the passenger list.
Another curious aspect of this passenger list is that the passenger
above Buna (line 21) is Schmerl Saubermann, age 27, whose passage was paid
by "brother-in-law Max Rosenbaum." Max and Dora have a brother-in-law
named Max Rosenbaum and it looks too interesting to be just a coincidence.
(Max Rosenbaum's great-grandson recently told me that he had, in fact,
helped bring other family members to the US.)
