I am doing some research for a family member in Canada and discovered a connection through her GGrandfather to your Ellerker Tree.
Philip Moonb1862 Wollaston Married Sarah Elizabeth Ellerker b1864 Shropshire. Her father was David Ellerker and mother Eliza Freeman. Also in the female line are the names Ranson,Sandvidge,Knugs/Knags.
I have the Ellerker line back to Thomas Ellerker b1680 Cherry Burton Yorks.
