I'm sorry that I'm only now reading your reply to my post for the first time after nearly 5 years!Since my original post was in 2001, I suppose I shouldn't expect to receive your next reply until year 2018!(kidding)
I do see that we are related through George Alder and Lucy Ann (Wynn) Alder of Prince Georges County, MD (later moved to Loudoun Co., VA).
George and Lucy's son James Latimore Alder (your Elizabeth's brother) is my direct ancestor.He went by his middle name, which was often spelled "Latimer" or "Lattimer".Latimer Alder served in the War of 1812 for which he later received bounty land, and he eventually moved to Iola, Allen Co., Kansas where he died at age 91 (year 1874).I visited his grave site in Iola some years ago.His grave was decorated many years after his death with a plaque presented by US Daughters of 1812.Although his gravestone, created at the time of death, was inscribed simply as "Latimer Alder", the plaque, unfortunately, gives him a middle initial of "E" which is incorrect.This erroneous middle initial has caused some confusion over the years, as it is often assumed to be correct.
Latimer Alder and his wife Catherine (Silcott) Alder had 9 children, including my 2nd great-grandfather Anderson Alder.Anderson left Virginia as a young man, long before his father Latimer migrated west to Kansas.Anderson married in Belmont Co., OH to Rachel Kemp, to whom he had 4 children.Rachel died in 1848, and in 1849 Anderson married Martha Hubbard, also in Belmont Co., OH. Sometime after their 2nd child was born in 1854 (Catherine Elizabeth "Kate" Alder), Anderson Alder and his family moved to Brown Co., IN, where he died in 1882.Anderson and Martha had 10 children, so in total Anderson had 14 children between 2 wives.I recently acquired Anderson Alder's family bible, which contains several old photos, including a very old tin-type photo of him.Your ancestor Elizabeth Latimore (Alder) Bradfield was Anderson Alder's aunt.
I'm happy to share whatever info I have that may interest you.
