:I have no idea who Jennifr(sic) M. Macleod is, or even if she actually exists, she certainly has not contacted me - how would she know who I am?  However, if she claimed your article "contained unsourced date" (I assume you meant data) she would be absolutely correct.  

 :I only came across the article on James Valitchka because it included the letter combination "reknowned".  As there is no such word as "reknowned",  I assume you meant "renowned", but the use of renowned is deprecated on Wikipedia, as it is a meaningless "peacock" term - please see WP:PEA. (I see below that Cluebot, one of Wikipedia's automatic bots, has since had to remove it again)  

 :Whilst removing the mis-spelling I noticed that much of the article on Valitchka does not comply with Wikipedia guidelines and policies. I initially removed the stray bold text (see WP:BOLD) and some of the external links in the bodytext (see WP:EL) I then removed the excessive use of first name as WP:SURNAME, I then formed further external links into references.  There still remains much to be done to this article, to meet Wikipedia standards. 

 :You then proceeded to add duplicates of the same information you had already added, which I removed.   

 :I note from your post above, that you are asking people to contact you for verification. Wikipedia does not work that way, the person adding the information has to cite the references when they add the information (see WP:CITE, and they need to be verifiable (see WP:V) and from a reliable source (see WP:RS). You, your website, your publishers press-releases etc. are not seen as reliable sources, as they are unlikely to be impartial. 

 :You have above admitted that you are James Valitchka.  This gives you a clear conflict of interest (see WP:COI) in editing the article at all - I suggest you read that policy carefully, and follow it, or you are likely to be blocked. 

 :Moreover, you appear to want to control what goes on this page - you cannot.  You do not own the article (See WP:OWN) and, to quote the text above the edit box you used to enter text "Work submitted to Wikipedia can be edited, used, and redistributed by anyone"-
