I think one of my biggest obstacles to citing all my sources is that I've been stuck on how to properly cite the records about myself and my direct family, so it felt like I couldn't really document my pedigree until I skipped to at least my grandparents, where I can find some "normal" records to cite. I'm specifically thinking of the marriage license & certificate that I possess for my own wedding, as well as the birth certificates for my children (attached image). This discussion (https://www.evidenceexplained.com/content/marriage-license-and-certificate-same-document) has been very helpful to describe them as privately-held artifacts, but I still have some questions. The current citations I have are:
 Simpson-Doan Marriage License and Certificate of Marriage, 29 June 1996; Simpson Research Files, privately held by Michael James Simpson, [(E-ADDRESS) & STREET ADDRESS FOR PRIVATE USE,] St. Joseph, Michigan, USA, 1996. Issued 17 June 1996 by Livingston County (Michigan) Clerk, local file no. 571128, state file no. 96-323.
 Samuel Luke Simpson Certificate of Live Birth, 18 April 2003; Simpson Research Files, privately held by Michael James Simpson, [(E-ADDRESS) & STREET ADDRESS FOR PRIVATE USE,] St. Joseph, Michigan, USA, 2001. Issued by the Washtenaw County Clerk on behalf of the State of Michigan Department of Community Health on 11 March 2004, no file number.
My questions are:
1) I have the original paper documents in a safe-deposit box, and have scanned images of them on my computer. Does the exact item format I'm referring to change the citation at all?
2) What is the significance of putting the city and state of me as the owner of the items? I've had multiple addresses over just the last ten years, so I'm wondering what someone reading this is supposed to learn from it?
3) Before citing them as private artifacts, I tried to apply the QuickCheck Models of Local (County) Vital Records and State-Level Vital Records, but wasn't sure which to use based on the jurisdiction. Both are state-level vital records, but they are issued by the local County Clerk, so which model applies?
Thank you so much,
