This is a typewritten manuscript, apparently self-published by an amateur genealogist. It contains only a few incomplete source citations, but there are numerous instances in which "obvious" inferences from indirect evidence are not given (e.g., will probate is listed but no estimated death date not given), suggesting that all of the facts actually stated are drawn from primary or secondary sources.
The document focuses on a particular lineage, but includes basic vital information (birth, marriage, death) on all siblings. It also contains a lengthy narrative (mostly unsourced) giving more information about the lives of the people in the primary lineage.
The Ancestry.com record has a 1988 publication date; maybe this is the microfilm date?
