This is what I have found. It was listed in the "Pennsylvania: The Foreigners Who Took the Oath Of Allegiance", I think that was the name of the book, on page 393. The website The Palatine Project Ship Lists has a several ships dating back to the 1600s, which the Ship Leathley is listed, but not much information. Most ships listed only men age 16 and over, but some ships listed men, women, and children. The Ship Leathley left Hamburg, Germany, then to Cowes, England, then to Philadelphia, Pennsylvania.
Note: The "*" after the name is my notes at the bottom not what was stated in the book. The "**" is the Schlencker's (Slinker's) that are my ancestors. Spelling of names are typed exactly how it is in the book.

The book states:

**SCHLENCKER'S: complete names I found and who I matched with above list.
1. Fried. Wilhelm Schlencker
Full Name: Friederich Wilhelm Schlencker
Name given on date above: Frederick Wilhelm Slinker

2. Christophel Schlencker (still researching full name)
Full Name: Christophel Schlencker

Note: I am connected to this Slinker.

3. Frantz Hen. Schlencker

4. No matches for this name above, unless he was under 16 or his name was skipped, I have no clue where this name came from.
(only guessing full name by German name list)
Full Name: Johannes William Schlencker
Name given on date above: John Wm. Slinker

***Note: John in German can be spelled-Johannes, Johann, Hans, Hanschen, Hanslien, Haensel, Hansl, and Haensele. Also, English spellings: John, Jack, Johan, Johnie, Johnny, Zane.
***Note: Wm. is usually William. In German, William can be Wilhelm, Willi, Willy.
These spellings came from a book that translates names to several languages. Sorry, I did not write the name of the book down.
Any quesions, you can email me at mammawhandley@yahoo.com, I hope this list helps you and others who are trying to find info on the Ship Leathley. I recommend checking out the Palatine Project Ship Lists website, some ships list ages for passengers. Although, I have not found a list for Ship Leathley that does have more info.
