As a general statement so that search engines might bring you to this place, please note that the Van Sicklens of New Lots, Kings County, Long Island, New York tended to use the spelling Van Siclen. The J. W. Van Sickle book looses sight of this part of the family; meanwhile he and Teunis G. Bergen mis-attribute the proper lineage.
If you are, or have an interest in, the specifinc descendants of Ferdinandus^1 VanSicklen who came to spell their surname Van Siclen, derived especially from Johannes Van Siclen and Gertrude Lott, please post here.
Many thanks in advance,
Richard A. McCool Descendant of Abraham^5 Van Siclen and Cornelia Cornell
