Samuel & Sarah.
William 19 Years- Birth of WILLIAM BARR in July 1890 Dromore, Co Down
Lizzie 15 Years – Birth 1892 Kilwinning, Ayrshire mmn Martin?
Sarah 7 Years – Birth 1902 Ardrossan New mmn Martin.
James 3 Years – Birth 1905 Dalry (Ayr) mmn Martin.
I believe Alexander was informally adopted by Sarah's sister below
ALEXANDER BARR mmn MARTIN 1901 Ardrossan New
15/07/1901(Thanks for the birth date)
Alexander & Isabella
Louisa Barr 1886 born Monkton and Prestwick
Isabella Barr 1889 born Maybole
Robert Alexander Barr 1892 born Maybole
William Martin Barr 1895 born Ochiltree
No other birth registrations, and no deaths of Barr children there after 1905.
Alexander Barr senior died 1913 Ochiltree age 60 (1853), as did
Isabella Docherty Barr nee Martin in 1937, if the age of 75 is correct she was 16 at marriage?
There are these two other birth registrations mother MARTIN .
ALEXANDER BARR 1896 Stevenston
BARR MARY 1907 Died 1908 Stevenston
I cannot find Alexander age about 5 on the 1901 census, no death, or possible parents.
