I'm not related....a volunteer I didn't find anything for Lula/Lulu BURCH, other than her marriage to your dad.There's always possibility she had been married previously and BURCH not her maiden name, unless the marriage license said "Miss" or "single".
I do have his info. Eddie B RUMFIELD b. 6-3-1921; d 4-15-1982 Snook, Burleson TX; Soc Sec card issued bef 1951 TX. Plus the b/dates of you and your siblings, but you know this.
