Lockhart Walsh Correia Families Elena Lockhart Researching the Lockhart S IN South Africa

According to some previous research the LOCKHART's originally landed in the Eastern Cape (Tembuland) region of South Africa and by the early 1900's the family had grown quite considerably. Any information would be appreciated. I am researching ELENA LOCKHART who married MATT WALSH about 1920 in Johannesburg. They had 4 children and many grandchildren. Someone must remember an Uncle David or an Aunty? Contact me ceciliawalsh792@gmail.com.
