Sandie LINDSAY was lately heir presumptive to his first cousin, the 3rd Baron (b 1945, m twice, no issue, resident in California)
His eldest son is the new heir presumptive: Simon Alexander LINDSAY, born 1963, m 1993 M Angeles PEREZ (of Spain), no issue found in BMD searches. Companies House records show him as a Partner in Bevan Brittan LLP, a legal firm.
This title is remarkably low on young heirs. Despite 9 males in remainder being born between 1940 and 1967, only one is shown by Debrett's as having any male issue (Sandie, of whom we treat); the only other issue known of these males is of Stuart Martin LINDSAY - 3 girls (and it was our group that uncovered this -
Lindsay of Birker collaterals). There is some hope that one of the grandchildren mentioned is in fact a new heir.
