Most published and online genealogies claim he was the Jehan Daillie baptized on the 7 Feb 1642 in the French or Walloon Church in Threadneedle Street, London, England, the son of Jean Daillie & Marguerite Madou. (Note it is not Madon as sometimes used - I have checked the original register and it is definitely Madou [LDS Film 466707].) Many websites also include the following two children in this family, Nicholas 1648 and Jean 1650, some claiming to a 2nd wife Sarah Willet married in 1648 in the Dutch Reformed Church of New York. However this marriage does NOT appear in the original church registers [LDS film #1927968] nor the transcripts available online (Olive genealogy & Internet Archive.) I have noticed a couple of internet sites where people have quite correctly questioned whether John Dally jnr was born in 1642 or 1650. If in fact John snr had a 2nd child named John this would infer that the 1st John had died (in most cases). Also if the 2nd child was to a different wife and indeed is the correct John then most genealogies are using the wrong maternal line of Madou, instead of the 2nd wife, possibly Willet?
Some web sites using the alternative of Jean / John born in 1650 quote a tax list from Virginia as proof. This tax list apparently shows a John Dally paying tax in 1666 with a son John Dally aged 16years or older. I have not yet looked at the original tax list to see the exact wording.
Much of what people have copied is from the book 'Staten Island and its people' by Charles W. Leng, publ. 1930 partly from information supplied by a Mr. D. S. Dalley of Plainfield, NJ. However no note is made in the book of sources, nor the origins of Mr. D.S. Dalley's knowledge, was it family lore or the result of research? This "recollection" has John Dally snr moving from New York to Virginia, then Monhegan Island, Maine, then Staten Island, quite a journey up and down the East coast, interesting, but factual?? This information has been copied with, it seems, no further research nor any documentation, sources, or argument to back it up.
Update - I have already found a discrepency in the Maine anecdote showing John Dally has been confused with a John Dolling. The John on Monhegan Island, Maine, is recorded as John John Dillon, Dollin, Dollen, Dolling, Dalling, occupation fisherman, inn holder & yeoman, from 1669 - 1688 (The Fortunate Island of Monhegan by Jenney who gives his sources). Importantly there is a document that records him as a resident on Monhegan in 1686 "John Dalling, of Monhegan, in the County of Cornwall, yeoman ...... whereon the said John Dalling now dwelleth" (NY deed - The history of the District of Miane by Sullivan). However his being resident in Maine in 1686 contradicts a New York deed from only the year before in 1685 for John Dally where he is recorded as a yeoman of Staten Island. This would seem to indicate that they are two different people in two different places at the same time, and for some reason at some time someone has decided that John Dolling etc. is the same person as John Dally. The other claim that John Dally appears in the New Amsterdam records in the 1640's is incorrect as they are records of John Dolling and hence can also be discounted as belonging to John Dally. Unless those who claim they are the same person can give some evidence or argument as to why they are the same person, something no-one does in their claims and in the copying and repeating of this "information", and without source documents or checking it for themsleves for authenticity, then it should be treated as unreliable genealogy.
He married Lysbeth OBBE.
The couple are listed in the New York Marriage Licences2 - Dally, John & Elizabeth Ober, Book - Orders, Warrants & Letters V.II pg. 223, 11 Aug 1668 (see explanation on NY marriage licenses). Most of the marriage license books were destroyed in a fire so the original entries cannot be checked. The marriage is does not appear in the published transcripts.
John & Elizabeth sold a property on Staten Island in 1685 (see Deed transcript). It appears they may have been short of money as they immediately leased the property back from the new owner (see Indenture transcript).
