I don't in any way mean to be negative about BD's work--I rely on it first for much of my own thinking.
But, "about 35" is not exactly precise enough I don't think.
Ted born in 1970 at her age 35 is probably workable--however her birth date in 35 makes her four years younger than Ted's father--which is certainly not impossible.
But to start looking at the fine print in the effective date clauses for the citizenship statute, a hard date would be better; maybe with some record document.
I would have thought that in the hotly contested Texas Senate race, someone would have been looking at this stuff.
Do my posts #77 (and math correction in #79) help?
They are a first cut at a worst case analysis, and a starting point to show where we need to fill in the gaps in the timeline:
When his parents got married (look 1962 to early 1970),
When they went to the job assignment in Canada.
Many thanks again!
Your point about state senate got me thinking .. what points germane to what we are looking at would have come up then?
