I have records of my Holcroft ancestors who lived in the Warrington district in the 19th century. Richard Holcroft, a draper, died in Warrington in 1822, and his son, also Richard, and also a draper, died in Warrington in 1860. His son Tryall kept a detailed diary, which is a fascinating account of life in the period 1835 until his death in 1880. His second marriage was to a Sarah Odell, and my grandfather, Alfred Odell Holcroft, was a son by that marriage. He emigrated to South Africa somewhere around the turn of the century. As far as I can establish, there are no other off-shoots of this line. I.e. if you and I are related, then the link must date back to Richard or earlier.
