Anna Marina : Earnest, if it was 1891 then that was the same year C T Russell wrote a letter that contained a reference to Baron Rothschild.
I presume you are referring to the letter Russell sent to Baron Maurice de Hirsch which was published in the December 1891 Watchtower in an article A New Government for Palestine Proposed. A copy of the letter was sent to Baron Rothschild as one of the "leading Hebrews of the World" and a leading proponent of the Zionist movement, promoting industrialization and economic development in Palestine.
Russell wrote the letter in August, 1891, while he was in Palestine "considering the prospects of the soon fulfillment of the predictions of the prophets" :
As you will see from my books, we find the testimony of the prophets to be, that your nation will be greatly blessed and returned to divine favor between now and the year 1915, A. D. ... We believe that the Lord's Word teaches that the people are to be in great part gathered into the land of Palestine.
Russell's suggestion was that wealthy Hebrews purchase from Turkey, at a fair valuation, all of her property interests in Syria and Palestine; i.e. all the Government lands (lands not held by private owners), under the provision that Syria and Palestine shall be constituted a free state.
Of course Rothschild would be included among the "wealthy Hebrews". Your implication this had anything to do with the Cross & Crown on the Watchtower cover is ludicrous. In fact, both Hirsch (who founded the Jewish Colonization Association on September 11, 1891) and Rothschild were largely involved in establishing Jewish communities in Ottoman Turkey, although not quite to the extent that Russell had proposed.
