As simple people search gives you all this. Looks like Eleanor Elizabeth Wilson Cruz Darragh was born about 1935 which made her about 35 when Ted was born in Canada in 1970. She got her degree at Rice University in Houston, TX. Looks like she probably does meet the requirement to pass on US citizenship.

She was born Nov 23, 1934 in Wilmington.
