In addition to ancestors from Canada, both Anglo-Canadian and some French-Canadian, my _known_ ancestors were English, Irish, Dutch, German, Alsatian, Scottish, Scotch-Irish (circumstantial but convincing), Danish, Belgian, Dutch, English/New England Puritan, and if you go back far enough, Welsh, Norman, & Frankish.

Then there is two x# Great Grandmothers whose background is in doubt.

One of my 6th Great Grandmothers, the wife of Ammannuel Mullinax and mother of Absolum Mullinax, is believed to of been either Native American or half Native American, half French, though we don't known what tribe, nor are we certaint of this. heh, You try researching backcountry South Carolina in the 1740s and see if you can do anybetter! No actually I'm serious, please let me know if you find anything :).
Some of the tribes in the area at the time (list not exhaustive): Catawba, Cherokee, Tuscaroora, Yamasee, also possibly Westo & Yuchi, likely others.

Then there is the identitiy of the mother of Anthony Jansen Van Salee The Turk. That would be my 11th Great Grandmother.
Given the conflicting information on Anthony's father, Jan Jansen van Haarlem, aka Morat Reis, aka this, aka that... It is perhaps not surprising that there are numerous theories.
1. The first theory, usually quickly debunked is that his mother is Jan's dutch wife, but this would not explain Anthony's appelations of "Mullato" & "du Turck" ('The Turk') nor his dark skin. The two main pieces of data supporting this seem to be the claim that Anthony was with Jan at Lanzarote combined with those sources (notably Van Dyke Roberts, which has some date errors) that had Jan as a merchant captured at Lanzarote by the corsairs, rather than any of the other explanations for his role at Lanzarote.
2. A second is that the mother is a gal from one of Jan's European ports of call, especially mentioned is Cartagena, Spain and a woman named Margrietje, though I have yet to see any source for this name. Others suggest that this unnamed women only raised Anthory, but was not his mother. Her ethnic identity has repeatedly been suggested as either a Moor (likely a Mudejhar) or Jewish, though the Jewish claim seems to be based on the fact that the names of the children are Hebrew, an argument I don't get, not everyone with a Hebrew name is jewish, i.e. not every 'Sarah' in the world is jewish, I'd bet that half or more of all the Sarah's out there in the world are not jewish. A big question I never see addressed is why would a pirate know for ruthlessly attacking Spanish shipping routinely be putting into a spanish port? The main claim for this seems to be that Anthony is mentioned on the marriage bann as a seaman from Cartagena.
3. The Third, and most accepted theory, is that Anthony's mother is the wife "given" to Jan by the Saadian Sultan of Morrocco, though the identity of this lady is also subject to disputing theories. 3a. Some have suggested this 'gift' was a slave, perhaps a black woman or a captured european slave. 3b. Other sources (which are themselves in question) say this was one of the Sultan's harem wives. This, to me, seems not only un-Islamic (though I am certaintly not a koranic expert) but unlikely. 3c. The third and most likely version of number 3 is that the 'marriage' was to cement or celebrate a political relationship between Jan & the Sultan though the leading thought amongst researchers now seems to be that this lady was either the daughter or sister of the sultan (depending on which sultan exactly it was, Moulay Zidan or his son), and as the Saadid's were Sharifian, thus the family tree can be extended all the way back to the Prophet Mohammed (making him my 34th Great Grandfather). I myself am wary of this proposal as it sounds to me to be too similar to a rush to connect to royalty in many other cases disproven. None-the-less this (3c) seems to be the dominant line of thought amongst the majority of those researching that particular line, though not without detractors, some pointing out a possible discrepancy with Anthony's age, and others who disbelieve the link between Anthony and Jan being son & father alltogether. Even if she was Morroccan, the question becomes Morroccan what? Arab? Bedouin? Berber? Black? Moor? Jew?
For either of the last two theories (2) the woman from Cartagena or someother port, or 3) wife "given" from sultan) various marriage dates are given, ranging from 1600's to 1630s, though one date commonly and routinely seen, 1608, is attacked because when combined with the date of Anthony's marriage bann (15 Dec. 1629) and his age reported in that bann (22) it supposedly rules her out as his mother. However, we don't know the date within the years in question so it very well could still work out, so I do not know why this date is always disputed, especially if you allow for A) mistake or rounding on the bann (I've seen worse age errors on US census reports!) and/or B) consider the fact that one or both of the dates was translated from the Arabic calender to the Julian calender and then possibly to the Gregorian calendar, hence it could be off by as much as two or even three years! Of course, on the other hand I've also seen no reason for this date. In summary, I don't know why this date of 1608 is always proposed nor why it is always attacked when it is proposed.
In all, I'm leaning towards either some version of #2 (though not Cartagena), or towards #3a, though I admit #3c is a possibility, though I'm wary.

UPDATE: following an email message I recieved, from someone who seems very knowledgable on the matter and situation, I am now leaning towards #3c more than #2 or #3a, however all attempts to reply and contact this informant have failed, so I am not fully convinced. I have however gone ahead and prepared a page on my ancestry assuming this Saadid descent, here.
