Attributed compiler of family information

I want to cite a single handwritten page of family information. It is one of three loose pages that were found in a Bible and sent to me. The owner had information about the compiler of each page – his grandmother, his mother, and let’s call her Mabel, a distant cousin. Mabel’s page is the most complete and the only one that contains the information I want to cite. It seems to me that Mabel may have had access to an older family Bible with specific birth, marriage, and death dates as well as spouse names for nine children (born between 1795 and 1816). The page of interest is labelled “Smith Family History.”  I question whether to name the attributed compiler, who lived from 1887-1977, and also whether to use the label as the source title. The way I initially crafted the citation, using the name of the probable compiler and the label she used, seemed to mislead readers to think there was more to the source than the single page.

My initial version:   Mabel Jones “Smith Family History,” supplied by [Name Withheld], Small Town, New York, 2017

I am now pretty certain the quote marks were a mistake. But would this revision be better?.

Smith family record (manuscript, one page, no date), privately held by [Name Withheld], Small Town, New York, 2017.  A photocopy was supplied to the author in 2017. The owner attributed the handwritten page of information to Mabel Jones, a descendant of John Smith. The page is labeled “Smith Family History,” and provides precise dates and spouse names for nine children of John and Sybil Smith, indicating the compiler may have located a family Bible. Birth dates and most marriage dates cannot be found in any other source, but the information generally checks out.

Additional information about all three pages and how each compiler descends from John Smith may go in the narrative or in the footnote.
