Burke's Landed Gentry of Great Britain:

Disappointing that some of these family histories are so inaccurate.
Clearly based on poor genealogies written without sufficient research or lack of knowledge. For example, the lineage of Ogilvy of Inverquharity for the 16th century is confused and erroneous. Does not cover the wives correctly and states that one of the lairds (Sir John Ogilvy) was succeeded by his nephew when in fact he had several sons still alive. He was succeeded by his grandson but the researcher did not understand that nevoy in Scots usage of this period means grandson and not nephew.
Says Sir John who sat in 1560 Parliament married Elizabeth Fothringham and had a son and heir John by her. Rubbish. She was my gtx13 grandmother. She married as second wife to John the father of he 1560 sitter. By him she had one son, Thomas who was the youngest of that John's sons. That laird died in 1547 and Elizabeth married secondly to John Ogilvy of Inverkeilor and had family by him and had a terce of Inverquharity, namely Kinnordy for her lifetime. There are too many other errors there to even try to correct them here. 

This is a very badly researched book which has numerous errors. Many of these errors could have been avoided with a little effort. For example, Herbert de Bohun Hogarth is NOT the son of the Rev David Hogarth. He was his grandson, son of the Reverend's eldest son David Francis. The Reverend did have a son called Bohun (no Herbert in his name) and Bohun died in India in 1877 following a trip to Australia where he was resident in 1876. Hazel de Bohun Hogarth is NOT the daughter of Herbert but his sister and she too, like Herbert, was born in India. In the 1901 census in the UK, she is living with her father David and her mother Lucretia (who is NOT the wife of Herbert). David Francis Hogarth and Lucretia Bull had married in India in 1869.
