Clarify wives and children of Martin Weybright Sr.

Martin Weybright Sr: Martin Weybright, Sr

Note in his profile says married in 1786 to Mary Elizabeth Geiger: Mary Elizabeth Weybright

Prior tree from Ann Bean lists Caterine Weybright (Jung) as wife of Martin Weybright Sr.: Caterine Weybright

 - death date is listed as 1783

Consider:

 - plausible that Caterine was 1st wife, who died; then Martin Sr remarried. 

Issues / Questions:

- Martin Jr is listed as born in 1787 on tombstone in Baintertown Cemetery (near Goshen) (See findagrave.com).  Hence can't be child of Caterine (as claimed by Ann Bean profile for Martin jr)

- "Memoirs of Indiana" claims that Martin Jr. is the oldest of Martin Sr.'s children. Hence none can be children of Caterine.
- Is it possible that Caterine has a son Martin, then both Caterine and son Martin died (and potentially a second infant), then Martin Sr. remarried and really wanted a boy named Martin?
