There seems to be some confusion over the wife(wives) of Joseph V. on other peoples geneology websites
The Sturge family website records that Joseph was first married to Sarah Sargent. She died,
then six years later, he married Mary Marshall.
Some of the LDS Church records- record it as one wife (Sarah Sargent Mary Marshall.) when it is actually 2 different wives.
there are also 2 individual records. see TIMELINE
