Methodology Monday with a Tom Jones puzzle

What can you make of these five pieces of evidence from Tom Jones's "Uncovering Ancestors by Deduction," National Genealogical Society Quarterly 94 (December 2006):287-304 (free PDF download for NGS members)?

1781: Ignatius Tureman's will names daughter Lucy and wife Eleanor.

1788: Obadiah Overton marries Eleanor Crow.

1796: Obadiah Overton puts up $150 bond for Lucy Tureman's marriage to John Kinzer.

February 1804: Elizabeth Crow, a minor and orphan of James Crow, requests that Obadiah Overton be her guardian. John Kinzer provides the bond for this guardianship.

August 1804: Guardian Obadiah Overton consents to Elizabeth Crow's marriage.

How are all these people related? Combining this evidence with knowledge of Virginia law at the time, Jones proposes a series of hypotheses and tests them using a deed that by itself makes little sense.

This puzzle is only the overture to the bulk of the article (and Jones's lecture "Inferential Genealogy"), in which the names of Eleanor Crow's parents are deduced.

If you can see how these puzzle pieces might fit together, without having read the article or heard the lecture, you may have the makings of a top-notch genealogist.
